ATTENTION! I advise you not to use “DriverPack Solution”, as, in addition to drivers, it installs a huge amount of garbage on your computer, which may cause it to glitch, slow down and work poorly.
If none of the above helps, then most likely you have driver problems and should be reinstalled. It is best to completely remove the device first, and then install fresh drivers. Otherwise, the computer will refer to the fact that they are already installed.
Connect your laptop or computer to the internet. Next, open the task manager (WinR = devmgmt.msc). Go to the section “Sound, game and video devices” and remove your audio card. You can delete all devices altogether.
Next, find the “Hardware Configuration Updates” button on the control panel at the very top and click on it. The drivers should be automatically downloaded from the Internet and installed on the computer. If this does not help, then remove the sound driver “NVIDIA” and “AMD” and do the same.
If these steps did not help, then it is worth updating the drivers for the video card and sound card manually. The fact is that not all drivers are available on Microsoft servers, and sometimes they are installed with an error. For installation, see the following instructions.
First, you need to find out the full name of the video card. To do this, in the same “Device Manager” go to the “Video Cards” section. Next, go to the “Properties” of your video and see the full name on the “Details” tab. Although the title can be displayed directly in the section.
Also, you need to know the exact type of your system. to do this, go to the “Properties” of “My Computer” and look at the line “System Type” (32 or 64 bit).
We go to the official support site. We expose all the parameters and click “Search”. Next, download the driver to your computer, install it and reboot.
We go to the official website. You can enter the full name in the search bar “search all products”. Or choose your video card according to the options from the lists. At the end, click “Send”. Next, you will need to select a system, bitness and download the latest “pack of firewood”.
If you have a built-in video card, then the drivers can be installed by ID. Since we still need to completely reinstall the drivers on the sound card, I will show how this is done on it. And then you yourself install the drivers for the built-in video in the same way (if your video is not from AMD or NVidia).
- We go to the section “Sound, video and game devices”. Find your sound card and go to its properties.
- On the Details tab, set Properties to display the Hardware ID. Right-click on the first line and copy the value.
- We go to any search engine (Google or Yandex) and enter two words: “Driver ID”.
- Next, go to the first link and paste the line that you copied into the search bar of the portal.
NOTE! If the drivers are not found, then simply select another portal for the same request.
- As soon as the drivers are found, download them and install them on your computer.
For those who have not yet reinstalled the drivers on the video card. do it in the same way. After this, the video should start streaming with sound.
Solving playback problems
Usually this problem occurs due to crooked or broken drivers. But sometimes the problem can be solved by simply turning on the audio stream in the “Device Manager”.
To quickly get there. look at your keyboard and find two keys on it: “Win” (may have a Windows icon) and the English key “R”. After you find them. press at the same time. An auxiliary window will open. write the command as in the picture below.
Open “System Devices”, now you need to find any line in which there is a mention of the words: “Audio” or “Sound”. the names may differ depending on the system and motherboard. Make sure that there are no arrows or crosses on top of this device. which means it is turned off. If there is one, then right-click and turn on the “Sound”. On some systems, it will be necessary to use, and not turn on the device.
If everything is in order with this device, then you can do this. Turn it off completely first, then activate it immediately. This method will help to reboot and load the drivers systemically, which will help solve the problem, and the sound may appear. check the sound transmission on the TV.
Go to the section “Sound, game and video devices” and find there any mention of “Audio”. this is the same audio output when using HDMI. If there are any arrows on top, then turn on the device.
If this item does not exist at all, then you can try to find it on the “Audio Inputs and Audio Outputs” tab. You can also look in the section “Video adapters”.
In general, we check all the sections that I wrote about above, and see that the devices with the inscription “Audio” are turned on. You can also try to turn them off yourself and then turn them on to reboot.
Checking your audio setup
First try turning off your TV and checking the cable connection. You can try pulling out and inserting the cable more firmly into the slot. Next, turn on the TV and check that the sound level on it is not at zero. just take the remote control and turn up the sound.
If you don’t hear anything, then let’s try to adjust the sound on the output device. In the tray, click on the PCM speaker and find the item “Sound problem detection”. The system will try to solve the problem itself. If this item is missing or the problem is not resolved. go ahead!
Find the speaker icon in the bottom right corner of the screen in the tray, right-click on it and select “Playback Devices”. The speaker can be hidden, then you will need to click on the arrow that points up. we look to the left of the main block.
On the “Top Ten”, you also need to click on the speaker in the lower right corner of the screen and select “Open Sound Options”. You can also get there if you simultaneously press the “Win” keys and the English letter “I” (Big “and” not “L”). then go to the “Sound” section.
Now in the “Sound” section on the right in the block, click on the link “Sound Control Panel”.
You should see a list of all playable devices. Here, in theory, there should be all connected devices, including our TV. Just find it, right click and select “Set as default”.
At the very end, click “Apply” and “OK”. If you do not see your TV set in the playlist, then right-click on an empty area in the window and turn on the display of disconnected and disconnected devices.
If you still do not hear anything and do not know how to output sound from a computer to a TV via HDMI, then we will try to solve the problem in a different way.
(There is a solution) Why does not sound go through HDMI to TV: how to output sound on Windows 7 and 10
Hello everyone! Today I decided to connect my computer to the TV, but there was a problem. there is a picture, but there is no sound through HDMI. over, in theory, HDMI should transmit both picture and sound, which means there are problems either in the TV set itself or in my computer. I still managed to solve the problem: when there is no sound through HDMI on the TV. and now I will tell you what exactly I did.
First of all, you need to check which HDMI port you connected your laptop or PC to. If the HDMI port has a “DVI” prefix, then it will not output sound, and it is intended only for connecting a laptop with a DVI-HDMI adapter, and DVI, as we know, cannot transmit sound.
You need to find a regular HDMI input with an “IN” prefix. In general, remember that if you are transmitting something to a device, then you need the input (IN), and not the output (OUT). You can also use regular HDMI without set-top boxes or HDMI (STB).
Also on the laptop, disconnect all connected devices. especially headphones and speakers, which can “pull the blanket over themselves.” There can be many reasons why there is no sound through HDMI on the TV:
- The main sound card for some reason does not switch the streaming audio output to your TV set. the problem is not serious and can be solved in two clicks
- The audio device, which is responsible for audio output and processing, has broken drivers. In some cases, they are not installed at all.
- Damage to the video card drivers. after all, we are connecting to it. That is, the computer should make sound output through the HDMI cable on exhalation, but for some reason the sound processing does not go.

Further instructions are suitable for computers and laptops with Windows 7, 8, 10 and even XP. If you have any questions or you notice an error, then write in the comments. You can also add your own solutions to the problem.
There is still no sound
If the sound from the computer does not play on the TV, then you can do one more thing:
- Check that the cable is intact without tears or fractures.
- Find another suitable jack on your TV and try connecting to it. Remember to route the signal to the correct output port on your TV.
If the sound was previously, but disappeared, then you can do something else. Try to remember if you have installed any programs before. Some programs may conflict with the built-in video card and audio drivers. Go to “Programs and Features” and remove suspicious software.
Check your PC with antivirus software, viruses could also be the cause of the breakdown. Go to “Startup”:
Xiaomi Mi TV (Box) No Sound. How to FIX?
Press “CtrlShiftEsc” to get into the Windows Task Manager.
Go to the “Startup” tab. disable all suspicious and unnecessary. If you do not know what to disable, then cut down everything except the antivirus program and the “Audio” sound driver.
Alternatively, you can try to do a system restore, but the drivers will need to be reinstalled. On the other hand, this may be the only correct solution if the system is broken. This is especially true when the sound was previously, but it abruptly disappeared.
Video card drivers
The first step is to make sure that there is a video card driver. it is he who provides the transfer of digital data between the computer and any HDMI signal receiver. It may seem counterintuitive to relate the video adapter driver and TV sound problems, but it is not. It should be understood that the audio signal is transmitted along with the video signal over the same HDMI cable, i.e. modern video cards have a built-in audio card. And for the latter to work, a separate driver is required, which is always included in the video adapter software package.
In any case, it will not be superfluous to reinstall or update the video card driver. The first step is to determine which graphics card is installed on your computer. The easiest way to do this is to use any PC component identification utility. For example. AIDA64. With its help, it is easy to identify the driver:
- Install and run the application.
- In the left part of the program window, find and open the section. “Display”, then go to the subsection “Windows Video”.
- All the necessary information will be displayed in the central part of the window.
Then it remains to go to the video adapter manufacturer’s website and download the latest driver. You can also download the drivers at NoDevice. Take a look at the image above again. The AIDA64 utility also provides a link (the “Driver downloads” item), by which you can go to the video card software download page. For example, to download the driver for NVIDIA products:
- Open the link from the AIDA64 program.
- Several drop-down menus will appear on the screen.
- In the “Product Type” menu, select the NVIDIA graphics card family, in this case. “GeForse”.
- In the “Product Series” menu, select a graphics card series, for example, GeForse 200 Series.
- Next, in the “Product” menu, select a specific video adapter model, for example, GeForse GT 220.
- It remains to select the version of the operating system and language, and then click on the “Search” button.
- A new page will open. Click the “Download” button to download the driver.
- Run the installer and follow the instructions on the screen.
SETUP REPAIR AND USE Samsung TECHNOLOGY
Samsung is one of the leaders in the sale of household appliances and mobile devices in Russia. In the last year alone, more than 1,000,000 units of various products from the Korean giant have been sold. Our site will help users in choosing, using and setting up Samsung equipment.
Choose your Samsung device following our tips and tests
Communicate, ask questions, get high-quality tech. support from site experts
The first step is to determine when exactly the sound problems appear. Generally speaking, there are only two situations:
- Or the lack of sound when the TV is operating in one of the modes it supports. receiving TV broadcasts via a digital and analog channel, playing videos from external drives (flash drives) and Internet resources, when using a computer as a video source.
- Or no sound when working in one of the listed modes.
Before repairing, any TV technician first “drives” the TV in all operating modes, which will allow to localize the problem. In the same way, you can identify the causes of the malfunction that have nothing to do with the operability of the TV itself. Let’s consider this issue in more detail.
No sound on digital TV reception
Digital television is understood as a television signal from a satellite dish or a TV cable brought into an apartment by a provider of relevant services. With this scheme of work, a receiver is necessarily used. a device whose task is to receive, process (decode and convert into the desired format) and further transmit the signal to the TV receiver.
Thus, there can be three sources of any problem in the digital TV scheme, including the lack of sound:
- Initial digital TV signal from satellite dish or TV operator cable.
- TV signal transceiver (receiver).
- Communication channel between receiver and TV (receiver output jacks, connecting cable, TV input jacks).
The easiest way to make sure that there is or is not a problem with sound when the TV is working as a digital signal receiver is to switch it to another mode.
- Press the “INPUT” button on the TV remote control.
- Select analog input (usually the menu item is referred to as “Antenna”), HDMI port, AV1, AV2, etc. as a signal source in the displayed menu. (depending on which input source is at hand. computer, DVD player, etc.).
- If there is no remote control, enter the main menu of the TV receiver from the front control panel, then go to the section “Input list”, “Signal source”, “Input device”, etc. (the subsection name depends on the LG TV model), select the desired item.
If the TV set has an Internet connection function, you can try to play any video or audio recording from the network. You can also connect a USB flash drive, computer, DVD player or other device to the TV set. If access to the Internet is not possible and there is no flash card or computer at hand, the TV can always be started in the mode of receiving an analog signal. This can be done even if the most ordinary television antenna is not available. In any case, sound will be heard from the speakers. at least interference.
If it was possible to establish that there is no sound only in the digital signal reception mode, one of the above nodes used in this TV operating scheme should be tested. In most cases, the source of the problem is the receiver or the cable that connects it to the TV receiver. All that can be done at home is to try rebooting the transceiver and reconnecting the cable.
Keep in mind that the receiver has its own settings, which you should definitely dig into. They can be reset to the factory defaults if necessary. How exactly to do this can be found in the documentation for the equipment or on the website of its manufacturer. It should be borne in mind that resetting the settings may lead to the termination of the broadcast of TV channels, i.e. receiver may need to be reconfigured.
What to do if audio is missing on your Samsung TV: causes and solutions
With old semiconductor Samsung TVs, sound problems were considered, perhaps, an exception, tk. they arose quite rarely. This cannot be said about modern television sets.
New TVs and Smart-TVs are more like a computer with built-in TV reception. And various problems with sound in any computerized device are quite common. Here are solutions to common problems that lead to loss of sound on LG TVs.
No sound when connecting the TV to a computer
If you do not take into account any malfunctions of the TV itself, then in this scheme of work, the source of the problem may be a computer or a connecting cable (usually HDMI). There are two ways to verify that the cable is working or malfunctioning. either by replacing it, or by connecting another device that supports HDMI signal reception (for example, a monitor) to the computer. If neither one nor the other is at hand, you should proceed to adjusting the parameters of the PC operating system.
Configuring Windows Sound Settings
Any modern computer has a built-in sound card and at least one speaker or headphone jack. If the motherboard has a built-in HDMI output or it is present in a removable video card, then the PC has at least two audio outputs. Any of these can be used as the default audio playback device in Windows. Through it, the audio signal will be output.
When connected to a PC TV, the system will usually automatically reassign the HDMI port as the default playback device. But sometimes this may not happen. In such cases, the HDMI output will not transmit audio. The same happens when you disable the audio playback function through the HDMI port. You can fix both problems as follows (for example, Windows 10):
- Right-click (RMB) on the speaker icon in the tray (lower right corner), then select “Sounds”.
- Go to the “Playback” tab.
- Find the icon with the image of the TV, signed as “Samsung”, right-click on it and select “Use as default”.
- The sound should appear.
- If there is no icon, right-click on an empty area of the window and check the box “Show disabled devices”.
- If there is a driver, an icon with the image of a TV should be displayed. Right-click on it, then select the “Enable” item, use the device as the default playback device.
No sound in any TV mode
- The TV has the wrong sound settings;
- Hardware or software faults.
It makes no sense to consider the sound settings of LG TVs, since the menu configuration is very different from model to model. Here you can use a general advice. to reset all settings to factory defaults using the appropriate function. In most Samsung TV models, this function can be found in one of the following sections of the settings menu:
- Go to the subsection “Settings”, select “Factory settings”.
- Subsection “Advanced”, then “General”, function. “Reset settings”.
- Subsection “All settings”, then “General” and “Reset settings”.
Many software problems can also be resolved by updating the firmware. For Samsung TVs with a built-in USB port, this is done as follows:
- Follow this link
- Select your TV model in the “Search by Product Category”.
- The page for the selected TV model will open.
- Click on the item “Firmware”.
- Download the file “Software_File”.
- Format the flash drive in the FAT 32 system (right-click on the name of the flash drive in Windows Explorer, then select “Format”).
- Create a folder on the USB flash drive named “Samsung_DTV”.
- Extract the contents from the downloaded firmware archive to the created folder.
- Insert the USB stick into the TV.
- A message will appear on the screen prompting you to update the firmware. Confirm the action, then click “Start”.
- The firmware will be updated.
If none of the things discussed in this article helped to fix the sound problem, the TV will have to be shown to a specialist.

Why is there no sound on the TV when connecting a PC via HDMI
Many users use HDMI to connect a laptop or computer to a TV. This is a very reasonable solution to expand the functionality of the device. However, sometimes problems arise. For example, when a PC is connected via HDMI, there is no sound on the TV. What to do in such situations?
You need to start with diagnostics. Determining the problem is not as difficult as it might seem at first. Incorrect sound transmission or its complete absence is due to several reasons:
- low volume level;
- hardware faults;
- outdated or missing drivers;
- incorrect playback device selected.
Absolutely every user can set up a connection. Now we will consider what needs to be done for this.
Checking the volume level
The most common and common problem. Therefore, if you are trying to determine why there is no sound on the TV when connected via HDMI of a computer or laptop, check the volume levels. Take your TV remote control and check if the Mute mode is activated. The volume may be set too low.
In situations where sound is not transmitted from the laptop to the TV speakers, you need to check the volume settings on the laptop. How do you do it? In the lower right corner there is an icon in the form of a speaker, click on it, and then lift the knob up. If the speaker is crossed out, then just click on it with LMB. Now you know how sound is output to TV via HDMI.
The lack of drivers on the computer is another reason for the lack of sound. Mostly the problem arises due to the fact that during the installation of drivers on the video card, the user has disabled the installation of components for the HDMI interface. As a result, it is not possible to transfer sound from the computer to the TV.
First you need to make sure that all the necessary software components for audio output are installed. Follow the simple step-by-step instructions:
- Hold down the WinR key combination on the PC or laptop keyboard.
- In the dialog box that opens, enter the command “devmgmt.msc”.
- Device Manager will start. In the menu located at the top of the screen, select the “View” subsection. Check the box “Show hidden devices”.
- Select “Sound, game and video devices”. A list of drivers appears. If, for example, only an audio card is displayed, then there is no sound on the TV precisely because of the lack of software components.
In some situations, the list displays the HDMI interface, but when the laptop is connected to a TV through this connector, there is still no sound. The problem is that the required component is disabled. Just activate it to fix the problem.
If only the audio card is displayed in the list of audio devices, then download the drivers for the video card. Install those components that provide sound transmission when synchronizing devices via HDMI interface.
Go to the official portal of the video card developer (Intel, NVIDIA, AMD), download the latest driver, and then start the software installation process. In the driver installation menu, select manual mode. Check the box next to “HD Audio Driver”.
Please be aware that the software component that transmits audio over HDMI is called the HD Audio Driver, but only on NVIDIA graphics cards. On GPU modules from other manufacturers, the driver may be called slightly differently.
Now you know how to set up HDMI audio if the driver you want is missing. The software components need to be updated periodically. Therefore, if the system offers to install a new version of drivers, be sure to agree.
Checking the playback device
No sound on HDMI connection is a common failure. Especially if the system does not automatically identify the connected device. To fix the crash, open the sound settings of the Windows operating system.
Hold down the WinX key combination on the keyboard. From the drop-down list, select the “Control Panel” item. After that go to the “Sound” section. First, you need to change the default view mode to “Small icons”.
Right-click on the speaker icon, which is located next to the indicator of the selected language, next to the notifications section. You need to switch to the “Playback Devices” tab. A new dialog box will present a list of available devices. If you are actively connecting headphones or speakers, you need to find other available methods. The playback method you need is called “High Definition Audio”. When you find the required method, select it, and then click on the “Default” button. Also, activation can be carried out using a similar command of the context menu.
All changes must be saved. If there is still no sound through HDMI, then try one of the other options below.
Another common cause of HDMI audio not working is hardware malfunctions. In other words, no sound is transmitted due to the failure of a certain module. How to fix the crash?
First, check if the HDMI cable is working properly. Perhaps the cable that is used to synchronize the TV and laptop is broken or the terminal base of the cord is damaged. The possibility of a partial wire break cannot be ruled out. If the sound is missing for this reason, use a different HDMI cable.
To eliminate the occurrence of such problems, it is wiser to use a DisplayPort-HDMI adapter, provided that it is a high-quality device. Cheap counterparts are not equipped with special contacts required for sound transmission.
Today, almost all TVs, Supra, Philips and others, have the function of automatically blocking the built-in speakers when connecting external speakers or headphones. If, when turned on, there is only a picture, and there is no audio, the first step is to check the ports. It is possible that external equipment is actually connected to the TV. Or, for a soundbar or speaker system, turn on the audio playback device.
The most common situation when a user turns off the sound on his TV himself looks like this: the user pressed the Mute button on the remote control to talk on the phone or not disturb others, and forgot about it. As a result, the TV turns on and there is no sound on it. However, on some models, the icon in the form of a crossed-out speaker is not displayed until the user starts adjusting the volume. The answer to the question of what to do in this case sounds simple: you need to press the Mute button or add the sound with the volume keys on the remote control or the device case.
No sound when connected via HDMI
All problems with connecting external devices have one explanation, which is suitable for most cases. this is poor contact due to oxidation of the connector or plugs. So, when you connect an external disc player via HDMI, there may simply be an open circuit on the audio transmission lines. It is clear what to do to check: inspect contact groups and, if necessary, clean them.
Another problem that sometimes occurs when connecting via HDMI is the wrong version of the cable. In this case, not only audio may be missing, but also normal video playback. You can find out which version of HDMI is supported by the TV and is recommended for use by referring to the instruction manual for a specific product.
Audio hardware problems
The audio system of a modern TV is a rather fragile technical device. It is carefully thought out, but not immune to emergencies. There are also problems of a purely hardware-time nature associated with component wear.
When listening to TV programs at maximum volume, the amplifier microcircuit may fail. For example, if there is a sharp drop in the level in the audio stream. Also, in some TVs, the speakers are connected in series. If one of them is damaged, the built-in audio system completely fails.
No sound on TV, only picture
This group of cases is the most extensive. It includes both physical hardware problems and options when there is no sound due to incorrect user actions. There are situations in which a Samsung, LG or Philips TV turns on and is silent due to SmartTV malfunctions. There are also purely temporary factors of accumulation of dirt and violations of the definition of the closedness of contact groups.
Sound is completely absent or unregulated
Software glitches often lead to audio processing problems. All TVs from different brands suffer from this. They can hang, work without audio, do not allow changing the signal source, and so on. Therefore, if the sound on the TV with Smart TV is not regulated, you first need to reboot it, that is, turn it off and on.
This simple solution helps in a lot of cases. But if the device continues to crash, it is recommended to do a factory reset or a full flashing.
TV sound problems: causes and solutions
If the sound on the TV is lost, it is both alarming and annoying. And there are quite a few options when such a situation is possible. For example, the sound on the TV skips when an external playback device is connected, or the speaker rattles and hisses. However, every situation can be explained. If at least in some version the TV turns on with sound, then the user can eliminate the reason for its absence on his own.
Sound dropped during TV operation
If the sound disappears during operation, the reason is usually the only one. microcircuit malfunction. When audio is present when the TV is turned on, but then abruptly disappears, and at the same time a characteristic burning smell appears, the microcircuit is burned out. This happens for several reasons:
- Voltage surges in the network. Stabilizers are installed on modern models, but over time they can wear out and fail. Followed by other hardware components.
- Unstable or low voltage in the network. Components do not receive the required energy, therefore they do not work correctly.
- Ingress of moisture. Hazardous situation that could cause damage to adjacent components.
Do not dust the device with wet or damp cloths. Microscopic droplets of moisture get inside. And if you turn on the device immediately after cleaning, something inside it will surely burn out. For prevention purposes, when cleaning, you need to use only dry rags, and also refuse to spray detergents on the surface of the equipment.
If the microcircuit fails, you need to quickly unplug the equipment from the outlet. It is also necessary to inspect the enclosure for any melted or smoking elements. Next, call the foreman, even if you have simple repair skills. Such malfunctions are complex, and it will not be possible to cope with them on your own without professional equipment and tools. In addition, burnout can damage or open adjacent components, and the slightest inaccurate action will lead to new faults.
If, while watching TV, there is a stable image, but the sound has disappeared, and there are no connected external devices, then there can be many problems, both technical and software. Software errors are resolved by downloading new software, updating the firmware. Sometimes the problems go deeper. in the software settings. They are extremely rare, but if they occur, then it is not recommended to eliminate it yourself. It will not be enough just to download and install the software in a semi-automatic mode.
As for hardware faults, the most common are the following:
- Failure of the power supply. If the rest of the systems are working, then the power supply has broken down partially, it simply does not supply energy to maintain the stable functioning of the sound system;
- Broken speakers or contacts not working. Speakers need to be replaced as they cannot be repaired. Or the wizard will test the contacts and rewire them;
- Defective ULF microcircuit (low frequency amplifier). Initially, when the microcircuit is not yet completely broken, sound appears when the TV is turned on. Then he can gradually subside or shut down abruptly. To fix the breakdown, the microcircuit must be replaced;
- Motherboard. Usually, if it crashes, all systems are unstable. As for the sound, it is unstable, sometimes it appears after turning on, sometimes when the TV is working. The motherboard is the most expensive piece of equipment, but the new board is cheaper than the new TV.
No sound when connecting external devices
If the sound disappears when you connect speakers or headphones, then the problem may be either in the connector or in the external devices themselves. To test the connector, you need to turn on several external devices. If they all don’t work, then it really is. If external devices do not work, you need to try connecting them to other equipment. Sometimes the connection cable also fails, especially if external devices are stored incorrectly. The cables are bent and the pins inside diverge.
When the external device is connected via HDMI, the situation is more complicated. The absence of sound in this case is often observed, but usually the reasons lie in the software:
- Check your settings. You need to go to the sound menu from the remote control, then redirect the signal source to HDMI. After that the audio tracks should work stably.
- Check the driver version. Many users do not update the software (they do not know what to do), which is why some functions do not work correctly. You need to go to the website of the TV manufacturer, check for new driver versions, and if available, download and install them. After installation, the TV will need to reboot.
