Connectors and cable
Before connecting, both devices must be turned off and de-energized. This is done for safety reasons. The computer and TV have almost identical jacks for HDMI cables, and they are located on the back of each device. For a PC, the cable is inserted directly into the video card, there are other options. For example, it can plug directly into the motherboard, and the connector is located next to the USB ports. The cable can be of various lengths. Both ends have the same connectors. When buying, you can choose and not very expensive, Chinese production. However, if you are going to run large files and watch high quality video (for example, in 3D format), then you will need a more expensive and high quality cable. HDMI version 1.4 or higher will do. There may be some difficulties when connecting. Before moving on to the problem when there is no sound on the TV through an HDMI cable, let’s consider another important issue: the options for connecting it. To ensure comfortable viewing of your personal video library on a new LCD or plasma TV, you need to consider where the cable jacks are located on the receiving device. For the TV that hangs on the wall, a cable with a plug that is at an angle of 90 ° is purchased. If there are not enough ports, then an adapter is required. The switch will help you connect multiple devices through one port.
Before adjusting the sound via HDMI, you need to adjust the picture on the TV screen. First, PC and TV are connected by DVI cable, then HDMI. “Cable not connected” or “Weak signal” will appear on the screen. Additional settings are available through the remote control. On it you need to press the “Source” button and determine the device that transmits the signal. A menu will appear on the TV screen, in it you need to select the port to which the computer is connected. Next, in the “Image settings” on the screen, the optimal resolution is set. Sometimes, when setting up a connection between two devices, you need to adjust the incoming sound to the TV via an HDMI cable. It should be borne in mind that both video and audio signals come through it. Therefore, setup may fail.
After completing all the steps described above, you can display the image from the computer to the TV. However, sometimes there are failures when connecting. The problem of how to connect sound via HDMI may arise if the drivers are not installed on the video card (as a rule, they are installed from the disc that is purchased with the computer). To check it is worth looking in the “Device Manager” in the “Control Panel”. There you need to select “Sound, game and video devices” with the cursor. In the list, click on the line that denotes HD sound support. When the TV is connected to the computer, the device will change its status to “Ready”. On it you need to right-click and select “Use as default” from the drop-down menu.
What if there is no sound on the TV via an HDMI cable connected to a computer?
For movie lovers, modern technologies provide ample opportunities to comfortably watch their favorite films. Yes, you can also use a computer monitor for this purpose. However, if you have a modern, widescreen LCD or plasma TV, then the temptation to turn it into a secondary monitor is great. over, this task is quite feasible.
Monitor and TV: Pros and Features
The computer and the TV are connected using a cable specially designed for this. This will allow not only to get more pleasure from entertainment (movies, games, Internet), but also to work. The TV receiver screen will become a “lifesaver” for owners of compact electronic devices: tablets, netbooks. Two high-tech devices, connected together, will allow, for example, to view movies in HD or Blu-Ray quality, photos, slides, work on the Internet. However, the connection may experience technical failures. One of the most common and frequent problems is that there is no sound on the TV connected via an HDMI cable. Consider options for how to cope with the task.
Other connection errors
The picture settings are set to the optimum resolution to match the specifications of your TV model. Now you have a great picture on the screen, but the question that there is no sound on the TV via HDMI may not lose its urgency. How can it be solved? With the mouse cursor, click on the “Start” button, select “Control Panel” from the menu. In Computer Options, navigate to Hardware and Sound, then click Sound. If it is absent in your computer, then you need to click with the mouse on an empty space. Select “Show connected devices” or “Disabled devices” from the drop-down menu. In the window you need to select the name of the TV brand. Now it should be turned on and off unnecessary devices (i.e. the computer). For the last operation, you need to right-click on the button labeled Realtek and select “Off” in the menu that appears. Let’s do the same with the “Speakers”. If there is no sound on the TV via HDMI, it is enough to follow all the steps described above and then, of course, you can enjoy watching the video in full.
Configuring Windows playback devices
Usually, when in Windows 10, 8 or Windows 7 you connect a TV or separate monitor via HDMI to a laptop, the sound will automatically start playing on it. However, there are exceptions when the playback device does not automatically change and remains the same. Here it is worth trying to check if it is possible to manually select on what the audio will be played.
- Right-click the speaker icon in the Windows notification area (bottom right) and select Playback Devices. In Windows 10 1903, 1809 and 1803, to get to the playback devices, select the “Open sound settings” item in the menu, and in the next window. “Sound Control Panel”, or through the Control Panel. Sound.
- Pay attention to which of the devices is selected as the default device. If it is Speakers or headphones, but the list also contains NVIDIA High Definition Audio, AMD (ATI) High Definition Audio or some devices with HDMI text, right-click on it and select “Set as default” (do this, when the TV is already connected via HDMI).
- Apply the settings you made.
Most likely, these three steps will be enough to solve the problem. However, it may turn out that in the list of playback devices there is nothing similar to HDMI Audio (even if you right-click on an empty place in the list and enable the display of hidden and disabled devices), then the following solutions may help.
Software shipped with graphics card drivers may also have custom HDMI audio output settings for supported displays.
And although this rarely helps, take a look at the settings for “NVIDIA Control Panel” (the item is located in the Windows Control Panel), AMD Catalyst or Intel HD Graphics.

If your TV has multiple HDMI inputs, use HDMI 1.
Well, that’s usually not necessary. It’s just that many HDMI 1 supports MHL, yes, due to this, problems are less common.
Sound disappears when starting any game. If you watch movies, etc., then everything is fine.
the headphones are all right. the matter is in the PC, updated the driver did not help, although I have headphones with a USB wire, this also does not help, I don’t know, maybe the case is in the green red connectors and in USB on both sides, maybe more in Windows, but where?
there was a problem when connecting the PC to the TV via HDMI. the sound was coming through the PC. And then it turned out that the administrator rights were blocked by Microsoft on Windows 10 initially (I already tried to get it in different ways described on the Internet, but it did not work). And “.msc” commands cannot be executed.
Please tell me what to do?
Thanks in advance.
I didn’t quite understand the situation that is. no user with admin rights? This does not happen in general Microsoft does not block anything in this way. (moreover, if it were so, you would not be able to install any programs)
I updated all the drivers, the picture is on via HDMI, but the TV is not detected in the playback devices.
laptop Acer swift3, Win10x64, Intel grafics 620, Realtek high definition audio (SST).
I already connect to the 3rd TV, it does not work. At the same time, other laptops work with these TVs.
I don’t understand what it could be.
No hidden and disabled devices.
For audio over HDMI, there must be drivers native to Intel graphics, not to sound. We tried to install them from the Acer website?
Yes, I put them, the very last ones. There are both video and HDMI audio drivers. After that, the video stopped working on the TV, the error came out, the resolution of the 720p type is not supported. I rolled back the drivers, updated both the video driver and the audio using Windows tools (the system independently searches the Internet). The TV began to show, but there was no audio.
is there something like “Intel audio for displays” in the device manager in audio devices? If yes, then select it. update the driver. select on this computer. from the list of installed drivers and there select NOT THE ONE that is currently installed.
By the way, I don’t know for sure (and I can’t check it now), but suddenly this “part” of the driver (ie purely for Intel sound via HDMI) is available somewhere separately from the display driver, it makes sense to look.
I tried to do everything according to the article, it didn’t work.
Booted from Linux (installed on a lubuntu stick) and no problems. Only in pulse audio switched audio output.
Sometimes you need to look for other ways besides Windows.
And if I now have only “Device.supporting” in the list of sound devices, what should I do then? thank.
Have you turned on the display of disabled devices? You can take a screenshot?
There is no sound via HDMI when connected, there is an image. The playback devices say. not connected. How to be?
And not through some kind of HDMI adapter connected?
the problem is that in the mixer it shows that the sound is on, but there is silence in the headphones, tried your methods, it did not help, in the same way, I thought in Windows the problem (10k is worth) demolished, still there was a problem
Good afternoon. The problem is this, I connected everything according to the instructions, the image went right away, the sound does not work either on the laptop (HP pavilion g6) or on the TV. Opened with the right mouse button the “playback devices” AMD HDMI Output is connected and it is already signed that this is the “default device” if you open it with the right mouse button there is no option to use by default. There is no volume scale next to this icon on the right.
Then there are “speakers and phones” signed as a device for communication by default and the volume scale is there but it is empty (even when something is played)
Then headphones for communication “ready”
When playing video, audio, YouTube, etc., there is no sound anywhere! Everything works “fine” in the device manager. Sound can be output to a laptop only if you disable AMD High Definition Audio Device in the device display.
Hello. Judging by the description, everything should work from ideas only problems with drivers, cable, well, or on TV the volume is removed to zero (although then the level in playback devices would be shown).
Hello, I connected the HDMI cable to the PC, the TV is installed by default as a playback device, but there is no sound, I use headphones (
Can you take a screenshot of the “sound, game and video devices” in the device manager and the list of playback devices? I may be able to help.
The following helped: parameters. system. sound. we find “Other sound settings”. device settings and application volume. reset settings and set the default values recommended by Microsoft
I disagree with the fact that it is impossible to output sound through an adapter or DVIHDMI cable. Electrically, DVI Single Link and HDMI are completely identical, and there is no separate audio line. There is a common line for control signals, along which sound is transmitted. Therefore, if a video card has an SPDIF input (old nVidia video cards from about 8800) or a built-in codec (all modern ones, including integrated Intel ones), nothing electrically interferes with sound transmission. I was convinced of this myself when I had to connect a GeForce 9400GT to the TV, which had an HDMI output, but only a DVI-HDMI cable was at hand. Although, of course, there may be some peculiarities of the layout of the video card or the implementation of drivers, when, when connected to the DVI connector, the sound output is forcibly prohibited.
The sound is not reproduced by the monitor speakers, HDMI-HDMI is connected, but if you connect the headphones to the back of the monitor, then the sound goes through them and is regulated by the monitor buttons
Asus rog gtx 1060 graphics card
phillips 237E7 monitor
all drivers are installed and updated
Is the sound via HDMI set as the default speakers? Is the volume on on the monitor? The speakers on the monitor are exactly working?
The laptop is connected to an HDMI-HDMI TV. There is no sound on the TV. I already conjured everyone, updated the drivers
Well, as the default sound output device on the laptop, what is selected?
regular speakers. disabled checkboxes are displayed. nothing but regular ones and there are no Bluetooth speakers anymore
So, for some reason, the drivers for sound via HDMI are not installed. they are included with the video card drivers, automatically (try to manually download and install the video card drivers).
Thank you so much! Everything worked out. All the best to you
There is no sound, I installed firewood on Nvidia, in the control panel Nvidia shows the TV in digital audio settings, and there is nothing in the sound except for the speakers, I checked the boxes to show disconnected and disconnected devices and there is nothing.
Did you install all the drivers (on NVidia)? It’s just that you can choose there and sometimes turn off the Audio setting. Sound devices have NVIDIA High Definition Audio in Device Manager?
And well, and more. purely theoretically. the HDMI cable is normal?
Help with the problem.
by spdif for some reason the last 15 years Realtek allows
transmit only 2 channels. there is a branch to Techpoverap with firewood
solving the problem, but there you have to dance with a tambourine and not always successfully.
There is another option, send sound to the receiver from an nvidia video card!
And here, too, for 10 years some kind of insanity has been going on.
Sound comes with picture only. And I need one HDMI video on TV, on another HDMI sound to the receiver.
Tell me how to put it into practice. Thank you very much for any constructive suggestions.
The task is clear, but I’m afraid I won’t offer a solution (and I can’t experiment, on a trip with a MacBook now). Of the ideas, except that the output of sound from the integrated HDMI, if available, but, again, there would be an experiment.
Good day! For two days I have been suffering, I can not solve the problem 🙂
After reinstalling from Windows 8 to Windows 10, when the HDMI cable is connected to the LG TV, the picture is transmitted, and the sound comes only from the computer. I tried everything. I demolished the video card and sound card drivers and reinstalled them again, nothing changes. But the most interesting thing is that I also reinstalled Windows from 8 to 10 on a laptop a month ago and everything went right there. That is, when HDMI is connected, both the picture and the sound can be heard from the TV speakers.
I am hope for your help
P.S. I don’t know how to attach a screenshot.
Take a look in the device manager, in particular in the sections
– audio outputs and audio inputs
– sound, game and video devices
Are there any devices in both places that are responsible for audio output via HDMI? They usually have in the name “high definition audio video card brand”.
If not, reinstall the video card drivers (exactly it) manually, and not in the device manager, and then make sure that the correct device is selected in the playback devices, see https://remontka.pro/open-playback-recording-devices-Windows- ten/
Hello. I have a laptop connected via an av receiver to a TV via HDMI, after I installed 10 instead of vin7 on the receiver, the sound disappeared. there is a video. I connected the laptop to a TV set, without a receiver, there is sound and video. In the Sound panel, the receiver is displayed, the equalizer responds, but the signal does not come to the receiver. What to do?
And the receiver is selected as the default output device after all, right?
If everything is so, I would reinstall the video card drivers (it is in them that the audio output via HDMI is implemented) manually (not through the device manager).
Thank you so much, human! Your article helped me a lot. Everything worked!
HDMI connection problem. The Samsung TV does not output sound from the stationary PC. I checked the cable by connecting it to a laptop. From the laptop to the TV, the image and sound come without problems. So I conclude that the problem is in a stationary PC. I reinstalled the video driver, NVidia 1080 Ti card, the driver is new, in the NVidia settings there is audio output to Samsung TV via HDMI. In general, there is video from the hospital on TV, but there is still no sound. Tell me what else you can do so as not to reinstall the OS. By the way, soit OS Win10Pro x64.
Hello. Is it checked here?. Right click on the speaker. Open sound options. Sound control panel. Is the correct device selected by default? Is the signal strength displayed on it? In the options (the “Configure” and “Properties” buttons), also play around, maybe he is there, say, 5.1 trying to display.
Hello. When connecting the NTV plus set-top box with a TV via an HDMI cable, the sound disappeared. There is everything from the bells. Other set-top boxes for TV work fine and there is sound and picture. I pulled the card out of the receiver, nothing changed, I did it before the factory settings. I ask for your help. I searched on the Internet, everywhere they solve the problem with connecting a PC.
Here I have no answer, I do not know the features of the prefix, although I suppose that probably all the same in its settings somewhere you need to look for something.
Hello Dmitry. 2 days ago I wrote to you the model of the set-top box, but this message disappeared. NTV prefix model OHS1740V100, release date 06/20/16. I looked in the settings, but the sound there in the preferences is audio / video, then digital video output, then PCM and Dolby Digital, I changed them, the sound did not appear.
Tatyana, I can’t advise anything on consoles and on this particular one remotely, not my specifics. Those. I myself, faced with a problem, would look for something in the settings, try a different cable, search on the Internet, in extreme cases I would call the manufacturer’s support phone.
Hello! good people help please! there is asus vm45e it has HDMI and display port. when connected via dp to a receiver or TV, everything works. When connected via HDMI to the receiver, it does not see the receiver. There is an image to the TV, but there is no TV in the playback devices. I would like to output the sound to the TV, so as not to turn on the receiver once again. there was Windows 10, put the seven. maybe the driver is needed or put back the top ten?
Install video card drivers manually. If Intel. from the Intel site, if AMD or Nvidia. from the respective sites. If two at once. then two at once. Inside them, and the HDMI audio output driver will be.
Intel HD Graphics 610, on the driver website for Windows 10
The HDMI standard allows you to easily display image and sound from a laptop or computer to an external monitor or TV. To transfer the picture and sound, it is enough to connect the computer to the device via a cable. But, as with any other data transfer standard, problems with HDMI can arise, including due to incorrect Windows settings. One of the common mistakes that users have to face is the lack of sound on the TV when connecting a computer to it via HDMI. There are several ways to fix this problem, which will be discussed below.
Please note: Before proceeding with the tips below, make sure that the lack of sound on the TV when the computer is connected to it via HDMI is not related to the settings of the TV itself. Often the reason is quite trivial. the TV sound is reduced to zero or the “Silence Mode” (Mute) is on.
The most popular method of connecting sound from a computer to a TV and not only. You just need to connect the HDMI output of the computer video card to the HDMI input of the TV and make a few settings. Short plan:
- We connect the cable.
- Checking the video card driver.
- Making audio output to HDMI.
For those who are not in the know, first you need the following cable:
Be sure to check for these connectors on your computer (video card) and TV. Older models often do not support it, but anything relatively new necessarily supports this popular standard.
There is nothing special to say about the connection: take the most inexpensive cable, connect the connectors, use it. Very often everything can work on its own out of the box, but most likely this is not your case.
Now you need to make an audio output to HDMI. To do this, right-click on the volume icon in the tray near the clock and select “Playback devices”:
On my Windows 10, the path was slightly longer:
- Click on the same sound, but select “Sounds”:
- Now all that remains is to go to the “Playback” tab, which opened immediately in the first option. This is where all the devices through which you can play sound are shown:
- We select our connected TV, right-click on it, in the new menu, select “Use as default” (see the screenshot above). From now on, the sound should go through the TV.
- First, make sure your video card supports HDMI audio output. Some of them do not support this feature. In my example, you can even go to Device Manager and see support from NVIDIA in the corresponding section:
- As an option, do not forget that after reinstalling the operating system, you can trust the automatic installation of the equipment, but it is better to go to the official website of your video card, download the latest driver and install it. Very often heals the problem.
If the sound from the laptop via HDMI still does not play on the TV
If both methods did not help, while the desired item is exactly set in the playback devices, I recommend paying attention to:
- Once again. check your TV settings.
- If possible, try a different HDMI cable, or check if the sound will be transmitted over the same cable, but from a different device, not from the current laptop or computer.
- In the event that an adapter or adapter to HDMI is used to connect via HDMI, the sound may not be able to make it work. If you are using VGA or DVI to HDMI, then definitely not. If DisplayPort is HDMI, then it should work, but on some adapters, in fact, there is no sound.
I hope you managed to solve the problem, if not, please describe in detail what and how happens on a laptop or computer when you try to follow the steps from the manual. I may be able to help you.
Installing drivers for audio output via HDMI
Another reason why there is no sound through HDMI on the TV is the lack of drivers. Most often, this problem occurs if, when installing video card drivers, the user manually selected the components to be installed and disabled the installation of drivers for HDMI.
You can find out if the drivers for outputting sound via HDMI to your computer are installed in the device manager. This requires:
Press the WindowsR key combination on the keyboard and write the devmgmt.msc command in the window that opens;
If only a sound card is listed in the list of available audio devices, you need to download drivers from the video card to your computer and install those components that are responsible for transmitting sound through HDMI. To do this, go to the Intel, NVIDIA or AMD website and download the latest video card drivers, then run their installation. At the installation stage, select manual mode and be sure to check “HD Audio Driver” among the available drivers.
Please note: The driver responsible for audio output via HDMI is called “HD Audio Driver” on the NVIDIA graphics card. On other maps, it may be called differently.
After installing the necessary drivers, restart your computer and try to reconnect it via HDMI to the TV.
Hey! In this article, we will try to connect audio from a computer to a TV. Why is this needed? Who knows you! Personally, I use a TV instead of a monitor and would like to output sound directly to it, and some like to listen to music through an audio system connected to the TV. In general, briefly and to the point for all occasions.
Still have questions? Any additions or suggestions? Do you want to share personal experiences for the benefit of other people? Leave your comment at the bottom of this article!
DVI and VGA
I hasten to upset you. only the video signal is transmitted through them. In the first case. digital, and in the second. analog. So we breathe out, calm down and move on.
No sound through HDMI on TV due to hardware issues
The second most common reason for no sound when connecting a computer to an external monitor / TV via HDMI is a hardware issue. It can manifest itself in two cases:
Defective HDMI wire. It is possible that the wire through which the devices are connected was previously pinched or its contact base was damaged. There is a possibility that there is a partial wire break or other problem;
An adapter is used to connect HDMI to an external playback device. For example, if DVI-HDMI or VGA-HDMI adapters are used, then the sound will not be transmitted through them. There should be no problems when using a DisplayPort to HDMI adapter if the adapter is made with good quality. Some cheap options do not have the pins required for audio transmission.
Restarting Windows Audio Service
An issue with HDMI audio output can occur the first time the system is started after a Windows 10 update. The Windows Audio service may not have started due to some inconsistencies that will most likely disappear after the next OS reboot. Or it is in an undefined state as a result of errors that occurred during the update, for example, when the computer was forced to shut down during installation. So try restarting it.
Open system services with the services.msc command. launched from a Win R window.
Find the Windows Audio service in the list, right click on it and go to Properties.
Make sure Automatic is selected in the Startup Type dropdown menu. Then click on the “Stop” button. After stopping, start it again.
After that, check if the sound is transmitted via HDMI to the TV.
Updating the sound card driver
Another reason has to do with a faulty or outdated audio card driver. Try to update it.
Display the Device Manager with the command devmgmt.msc from the Win R window.
Expand the Sound, Game and Video Devices tab. Right click on the audio device and select “Refresh” from the context menu.
In the next window, run an automatic search for updated drivers. If the system detects a new version, it will automatically download and install it.
If this method does not work, go back to the “Sound, game and video devices” tab, click on the audio device again and select “Delete”.
After uninstalling, restart your computer. When Windows starts, it detects hardware without drivers and re-initializes their installation. This will install a generic driver.
If a separate sound card is installed, go to the provider’s website and download the latest software and install it.
If, after unpacking the downloaded file (archive), there are no executable installation files of the exe type, click on the sound device again and select “Update”.
Search for drivers on this computer manually, in the next window click on “Browse” and specify the folder with the downloaded files.
Complete the installation and restart your computer. Check if audio is coming from HDMI to TV.
Why isn’t audio streaming to my TV via HDMI from my Windows 10 computer?
The peculiarity of the high-definition multimedia interface or HDMI is that you can use a widescreen TV as a monitor for a laptop or computer with Windows 10. However, when connecting through this interface, there may be a problem with audio transmission. Find out in more detail why Windows 10 does not transmit audio over HDMI and how to fix this problem.
Sometimes a problem occurs due to poor contact and in this case it can be quickly resolved. Therefore, before applying the solutions, turn off your computer and TV, unplug them from their power source, and unplug the HDMI cable. Reconnect the PC to the TV. Turn on your TV, then your computer. Also in the TV settings in the “Sound” section, check that the output is configured using the HDMI interface. If no sound is transmitted, follow the instructions.
Setting the default HDMI device
The issue can be resolved by setting the HDMI device as default in playback settings.
Open sound settings with mmsys.cpl command from Win R window.
In the Playback tab, right click on HDMI and set it as default.
If the audio device is not in the list, right-click on an empty field to bring up the context menu and check the Show disconnected / disconnected devices option.
Enabling the High Definition Audio Controller
Sound may not be transmitted via HDMI because the associated High Definition Audio controller is disabled in the system. To enable it follow the steps below.
Right-click on the Start button to bring up the auxiliary menu and select “Device Manager”.
On the View tab, click on “Show hidden devices”.
Expand the System Devices tab and locate the High Definition Audio Controllers. Right click on each and select Enable. Then check if the problem is solved.
As mentioned above, driver problems can be another cause of the problem, which is covered in this article. First, you need to understand how to generally establish the fact that the problem lies precisely in the drivers.
Problems with them will be indicated by exclamation or question marks next to the device icons in the device manager.
If there is a question mark, it means that the driver is not installed at all, and if there is an exclamation mark, it means that the driver is there, but it does not work correctly. For example, it can be damaged by viruses. In addition, an exclamation mark may indicate a driver update is required. In any case, if you have problems with the drivers, you should proceed to installing them. Let’s try to consider how to do this on Windows 7 and Windows 10.
Why is there no sound on the TV when connected via HDMI cable and how to fix it?
In recent years, the TV has long ceased to fulfill exclusively its direct purpose. Today, new models of these devices are also monitors, but with a significantly larger diagonal than models that are made specifically for computers. For this reason, these days, computers, tablets and other equipment are very often connected via the HDMI connector and the corresponding cable to the TV, which allows you to output the image and sound to it. But it so happens that there is either no sound at all when connected, or it disappears over time. Let’s try to figure out why this happens and how to fix it.
Selecting the correct playback device
As described above, it so happens that the reason for the lack of sound when the computer is HDMI-connected to the TV is the wrong computer selection of the playback source. As already mentioned, the Windows operating system performs the detection of the playback device on its own after connection. And the automatic selection is not always correct, which is why it has to be reconfigured manually. To select the correct playback device manually, you need to do the following:
- to quickly open the “playback devices” window, move the mouse over the volume icon and right-click on it. you can see several items, you should find “playback devices” by clicking on them with the left mouse button;
- now you should find the item with the name of the TV;
- you need to click on the “Use as default” button;
- waiting for “Apply” to save your choice.
If you do not see the item with the name of the TV, then you should click on an empty space with the right mouse button, where you will need to find the item “Show disconnected devices”. If there is a TV among them, then you need to find it and follow the above steps. Note that this tuning algorithm is suitable for both Windows 7, 8, and 10.
Checking the volume levels on the TV and computer
Now let’s try to figure out how to check the levels and adjust the desired volume levels or even turn on the sound if it is turned off. First, let’s do it on a computer. To do this, open the panel with volume levels. You can do this by clicking on the speaker icon to the left of the date and time on the right side of the Taskbar. If the sound is at a minimum, you need to increase the volume using the slider to a comfortable level.
Now you should click on the sound icon with the right button and select “Volume Mixer”.
A new window will appear where you can turn on the desired volume level for the TV and the running program. If you are using a laptop instead of a personal computer, then there you can also increase the volume in hardware. To do this, you need to hold down the Fn key with one of the keyboard buttons, which shows the loudspeaker icon. They are different for different manufacturers. A window with a level will open in the upper left part of the display, which can be switched higher by single pressing the specified key combination.
Also, check the sound on your TV. To do this, you can turn on any channel and press the volume up button on the remote control. Make sure the TV is not in some kind of silent mode. If the audio stream is present, then the device is working properly. If not, then you should contact the repairman. If, for some reason, the remote control is not at hand, then you can use the volume up buttons on the back or front of the TV, depending on the model.
For Windows 10
In Windows 10, the installation algorithm will be almost identical, with the exception of a few moments, because of which there is no point in repeating it again. But here it is necessary to note a number of nuances that can confuse the user. The first is that Windows 10 has a system that automatically downloads or installs the most appropriate drivers immediately after the computer connects to the Internet after installing it. Because of this, a problem often occurs in which the system does not show any problems with the driver, but it is not fully installed. That is, the driver itself will be installed, but the manufacturer’s interface will not.
Because of this, competent control of the driver or its settings cannot be performed.
Another aspect concerns the fact that it often happens that when a system is asked to update drivers, it will claim that the installed driver is the last one. But you can go to the website of the official manufacturer and make sure that this is not the case. So we advise you to download drivers only from the manufacturer’s official website and periodically check it yourself for new driver versions.
For Windows 7
So, if you need to download and install drivers on Windows 7, then you should do the following:
- first, you should go to the official website of the video card manufacturer;
- after that, in the appropriate forms, you should select the type, series and family of the device in the appropriate menu;
- now in a new window it will be necessary to indicate which operating system is on the computer, as well as in which language the installer should be;
- after that, a link to the latest driver package for your video card will appear on the site, which will need to be downloaded by pressing the corresponding key on the screen;
- after the driver is downloaded, you need to enter the “Downloads” folder, where you will need to run the installer;
- now you should select the necessary driver components that you want to install, and then click on the corresponding button, you will need to check the box next to the item “HD Audio Driver”, because it is he who is responsible for transmitting sound via HDMI;
- now it remains to wait until the installation is complete;
- reboot the personal computer and see if the problem is solved.
First, let’s try to figure out why the sound disappeared or why it just isn’t transmitted through the specified type of cord. So, the first reason why the sound does not go to the TV may be hidden in the fact that the silent mode is activated on the TV using the Mute key. Alternatively, the volume level can be set to the very minimum. The problem is often solved very simply. By the way, it will not be superfluous to see how many HDMI ports the TV has.
If it is not alone, then you can connect the wire to another connector of this type.
Another reason is feeding sound to a completely different device. This problem is typical for computers that are running the Windows operating system. So, this operating system has one property. when making changes to some settings, installing updates, connecting equipment and other actions, the device to which sound is supplied may be incorrectly selected. That is, if the computer has several devices that can play sound, then the operating system can choose the wrong device as the “correct” one. That is, it may turn out that the sound is in the PC speakers, but it cannot be output to the TV.
The third common problem due to which the TV does not play sound when connected to HDMI is the most common lack of the necessary video card driver. precisely, we are talking about the component that is responsible for the sound output through the HDMI connector. Or it can be installed, but not updated to the newest version, which is why it does not work correctly. At the same time, it often happens that the user seems to have installed the required driver, but did not check the box on the necessary component during installation, which is why the driver was installed simply without it.
Another fairly common problem is that you simply need to configure the sound in the control center directly by the driver, which is responsible for outputting sound to the TV. The fact is that often drivers of this type contain their own control centers, where there are various settings for use with connected audio and video equipment.
Well, it also happens that users simply confuse the HDMI interface with some other and connect via VGA or DVI. These types of cables do not allow the transmission of sound to the TV, which easily explains that it does not reproduce it. Or the connection can be made via HDMI, but using adapters of the specified standards, which also do not transmit sound. It happens that the cable is simply not detected. The reason it doesn’t work is likely to be physical damage.
What to do if all else fails?
Suppose that all the above actions did not bring the desired result, and still, when you connect a computer or laptop via an HDMI cable, there is no sound on the TV. First you need to take another HDMI cable and try to connect the devices to them. The problem with this type of cable is often that there is physical damage in some place, but due to the fact that the wire is hidden by a layer of protection, it cannot be diagnosed by eye.
You can also try connecting another computer to the TV. If everything works, then the problem is in the computer. and you can already look for the problem on this particular device. Another option for how you can proceed is that if you use some adapters, then one of them may simply be faulty. In such things, it is not recommended to use adapters at all, because often they just do not support the possibility of sound transmission in the cases under consideration.
If there is any additional software that is designed to control the adapter, you should take a closer look at its settings. It is quite possible that the operation of the specified device is simply not configured correctly. Also, either the TV itself or its HDMI port may be faulty. To do this, you can try to connect another device to it, replace the cable, or connect a laptop, computer to another TV, which will make it possible to determine the source of the malfunction with a high probability.
As you can see, there are quite a few cases when, when connected via an HDMI cable, there is no sound on the TV. But with a certain desire and some skills in the field of working with a computer, it is quite possible to fix such a problem.
What to do if HDMI audio does not work, see below.
Sound too quiet
When connected to a laptop TV, the reason for the quiet sound may be related to the settings of the latter.
The inability to increase the volume, despite the fact that the control on the remote control is set to maximum, indicates a breakdown of the radio channel or control processor (needs to be changed). Memory failure may also be the cause. Diagnostics and repair of the TV will be required.
Reasons why there is no sound on the TV
Breakdown can be caused by many reasons, and improper handling of the device is far from the main one. Build quality, service life and operating conditions, model features, etc all this can be a trigger for problems.
Accidental self-mutilation or setting the volume level to minimum are common reasons for the loss of a sound signal. If, after clarifying these points, the sound did not appear, the reason is much deeper. What can be attributed to the lack of sound on the TV. more.
Important: Having no experience in repairing plasma TV monitors, as well as in case of impossibility to fix the problem yourself, it is better to contact the technical service.
Loose contacts and connectors
On the panel of TV monitors (mainly on the back) there are connectors that are used to connect an additional headset: headphones, mobile gadgets, computers, etc. Regular reusable connection and disconnection of equipment over time leads to wear, poor contact and loosening knots.
The reason why the sound on a Samsung TV or another brand has disappeared is that the contacts have moved away from the connector.
What to do to fix the problem yourself:
- Remove and check the plugs that connect to the speaker.
- Verify the presence of a signal at the output of the microprocessor.
- Check if voltage is supplied to amplifier.
- Tap lightly on the speaker cone. maybe the contact has come off.
- Using an indicator screwdriver (working side), touch the amplifier input to see if the signal is reaching the speakers.
Caution: This is how you can find the probable causes of breakdowns, but you need to perform the actions with great care so as not to get an electric shock.
If the contact nodes are broken, the situation can be resolved using a multimeter, for example, NEO 94-001, (a special electrical measuring device), which will help find the damaged part. In the case of a broken connector, it can be removed and replaced with a new one.
Broken speakers or a connector may be a factory defect or mechanical damage. Improper monitor assembly is another factor that can cause loose contacts. When connecting via cable, it is important to check the speaker setting on the monitor.
Missing sound while watching
The reason that could cause problems with sound is damage to the microcircuit. precisely, its burnout due to voltage surges, overloads or poor-quality power supply. You can calculate the problem by the unpleasant smell of burning, which appears immediately after the loss of sound.
You must immediately disconnect the TV from the mains and make sure that there is no fire. After. seek help from the master. It is not recommended to repair the damage on your own.
The microcircuit can also be damaged due to moisture getting on it. To wipe dust off the TV, some users use a damp cloth or spray bottle. The risk that moisture gets inside and spoils the microcircuit is, albeit small. Situations are best avoided as replacement parts for modern LCD or plasma monitors are expensive. If the microcircuit was nevertheless so damaged, it is worth calling the wizard. Self-repair can be dangerous for the user.
If there is no burning smell, but suddenly the sound on the TV (LG or other) disappeared, you can try to disconnect the TV device from the network, wait up to 10 minutes and then turn it back on. If the sound appeared. the reason could be overheating of the TV or a malfunction of the microcircuit.
No sound when turned on
May be caused by poor contact between the speakers and the TV motherboard. In this situation, you can try to turn off and turn on the TV again, if the result is the same. you need to look for the reason further.
Check if the speakers are working properly. You can try connecting headphones, then speakers. If the problem is not with the connectors, it is possible that the speakers have simply reached the end of their useful life. But in the case when the TV was bought quite recently, the reason is clearly a factory defect or mechanical damage.
Another, albeit infrequent, reason is the breakage of the part of the cable that is responsible for audio transmission. In this case, a cable replacement is required.
Sound comes later
When you turn on the TV, there is no sound, but after a couple of seconds it appears. The result of a malfunction may be speaker breakage, loose connectors, or poor contact between the device modules. All worn parts must be replaced.
What to do if the sound on the TV is missing. 5 topical reasons and tips for troubleshooting
Home TV sound can be lost not only with older models. Users of modern TV monitors purchased recently may also face this problem. The reasons can lie both on the surface and hiding inside the device. Why there is no sound on the TV and what can be done about it. in the article.
Checking all faults according to the list. checklist
In order not to have to carry the monitor to a specialist in vain, you first need to make sure of the following yourself:
- the volume level on the remote control is higher than one;
- mute mode is inactive (the button must not be pressed);
- the signal source is working properly. some TV channels can sometimes be broadcast without sound;
- in the settings there is the correct sound output. speakers;
- no other equipment is connected to the headphone jack;
- the remote control is working. perhaps you just need to replace the batteries;
- speakers are not disconnected.
After making sure that all the items on the list have been passed, but there is still no sound, you need to evaluate possible household breakdowns:
With the help of these tips, you can establish the reason why the sound on the TV disappears, and even eliminate some yourself. With regard to mechanical damage (malfunction or defects in parts), you will need the help of specialists. Unqualified intervention can only aggravate the problem and lead to failure of the device, or even harm the user.
