How To Output Sound From Computer To TV

Step by step instructions for connecting

The principle of connection is SIMple, but for clarity, we will still consider its main stages:

  • Connect the cable to a port on the computer. All more or less modern laptops and system units on the back of the device have a special connector. He may be there one or several. You just need to insert the cable into the connector.
    How To Output Sound From Computer To TV
  • We connect the cord to the TV. On popular TVs Samsung, LG and others, the HDMI jack is located on the back. Most likely next to it there is a marking indicating the type of connection. HDMI. It will still not work to mix up the ports, since the cable will only enter a specially designed connector.
  • We set up the transmission of sound to the TV. This procedure requires more steps, therefore it is considered separately in the next section.

After connecting the cable and turning on the devices, no sound is output to the TV. Now there is no sound through HDMI to the TV. since Windows and Smart TV do not have proper setup.

How to output sound from computer to TV? detailed instructions

Before outputting sound from the computer to the TV. you have to get the right cable and do some SIMple system settings. With such minimal financial and time efforts, it is possible to save money on the purchase of speakers, because most TVs have good built-in speakers. Below are all the details you need to know about how to set up Windows 7, 10 and choose a cable to connect devices.

What to do if the sound has not appeared?

There are a number of issues where audio still does not come to TV.

Possible causes of failure

Why is there no sound through HDMI on the TV:

  • The volume is too low or the sound is muted;
  • The system does not detect the TV due to random error or faulty driver;
  • Disabled sound controller;
  • Wrong port used for connection;
  • Incorrect sound card operation.

Setting up TV sound

Time to get to the software side of the connection setup in Windows 10:

  • We sit down at the computer, right-click on the speaker icon in the taskbar and select “Playback devices”.
  • In the window that appears, we find an element with the name of the TV, sometimes it calls “Digital Audio (HDMI)”.
  • Right-click on the element and select “Use as default.

Perhaps now the TV will work as a sound source. This may not happen, in which case you will have to perform additional TV setup.

  • Open the TV menu.
  • Select the section “Sound”.
  • Specify as HDMI signal source.

Important! If multiple HDMI cables are connected, you will have to choose the one that comes from a specific computer. Here you need not to get confused and follow the designations in the settings or be guided by the markings near the active port. There is often a number or other designation of the connector.

If everything was done according to the instructions, the sound should appear. When playing any sound file, the audio will start playing from the TV. True, not always everything goes smoothly, but we also have solutions for such cases.

Recommendations for choosing a cable

Unfortunately, you won’t be able to wirelessly output audio through your TV anymore. Previously, there was special software with which it was enough to connect the TV to Wi-Fi. It’s better not to waste your time trying to output audio wirelessly now. You will have to purchase a special cable. The best of its kind is the HDMI cable, which provides digital signal transmission. In “digital” you can transmit and. and a sound track, and with an analog connection. only.

How to find a good HDMI cable:

  • Don’t skimp on quality. Cord from China, of course, is much cheaper, but its quality can be extremely low. Sometimes the distortion is so significant that it is SIMply impossible to enjoy clear sound with a picture.
  • Purchase a long cable. It is better to have a headroom than to face a lack of length. An ordinary plastic tie will remove the excess cable and hide it behind the TV. If the cable is not long enough, you have to buy an extension cord (it spoils the signal quality) or change the environment. Both are undesirable.
  • Make sure the cord is intact. It is important to pay attention to the integrity of the shell, the absence of mechanical damage, traces on the wire and the condition of the connector.


Troubleshooting the listed issues will help restore sound.

Brief description of the fix methods:

  • Checking sound on devices. On the computer, click on the speaker icon near the tray and check that the sound is on and the volume is above 50%. We take the remote control from the TV and turn up the volume.
  • We restart the search for connected devices. The easiest way to do this is to restart your computer. There is no need to disconnect the cable during power off and on. After restarting, the system should detect the device and install the driver for it.
  • Turns on the High Definition Audio sound controller. For some unknown reason, it may be turned off. To do this, press RMB on “Start” and go to “Device Manager”. Expand the “System Devices” tab, right-click on this controller and select “Enable”.
  • We change the port. The HDMI connector is different in several types. If HDMI is written on the back next to the port, and the audio in DVI brackets will not work. Switch to a different HDMI port;
  • Install new drivers for the sound card. In the documents to the computer or from the “Device Manager” can find out which audio card is in the system. We enter its name on the Internet and download the drivers from the official site. Run the resulting file. Sometimes, new drivers cannot be installed on problematic ones, in which case you will have to remove the old hardware, again from the “Device Manager”.

In addition to the listed causes of the problem, physical damage cannot be ruled out. A visual inspection will tell you if there is a problem with the cable or ports. Since it is mainly a problem in the system part, we will not focus on mechanical damage. We hope the instructions for connecting and troubleshooting were clear and detailed enough. However, if something is not clear, we are ready to help, ask questions in the comments.

How to output sound from computer to TV

How to output sound from a computer to a TV is a task that will allow you to avoid unnecessary spending on speakers and at the same time save your workplace from cluttering up with unnecessary devices. It requires some knowledge, which will be discussed in this review. The theoretical part will not take much time, and the practical implementation will require small material investments.

Connection procedure

The connector for connecting an HDMI cable on a computer device is located directly in its card and is routed, as a rule, on the rear panel of the system unit.

On the television receiver, all contact sockets are located on the back side and have a corresponding symbolic or letter designation (in our case, HDMI). In principle, it is difficult to confuse it with any other, it has a rectangular elongated trapezoidal shape. So, we connect the corresponding connectors of the cable purchased in advance:

  • To the system unit.
  • To TV input jack.

We turn on both devices and, naturally, we do not hear music tracks on the computer from the TV speakers. Do not worry, it should be so, you have completed only the mechanical part of the connection, after which you need to make the appropriate settings.

Beep setting

To play the audio signal transmitted through a connected cable by a computer device to a television receiver, you must open the corresponding settings menu in the latter:

  • Select section sound settings.
  • Activate the source as a signal from the HDMI jack.

Some TV models may have several analogous outputs. Each of them has its own designation (usually digital), it is imperative to activate the one to which the cable is connected.

If all connections and settings are correct, the sound file running on the computer should play through the TV. In this case, the volume can be adjusted both on a PC (speaker icon on the desktop), and using the TV remote control or the corresponding receiver buttons.

Choosing a cable for signal transmission

Unfortunately, the corporation (I will not advertise it again in this review) has stopped supporting (updating) the software that allows outputting the audio signal to Smart-TV in a wireless format. Therefore, do not waste time on useless attempts and start looking for a special cable. The best option is the HDMI model, which is capable of transmitting a signal in digital quality. When choosing, one should be guided by the following mandatory criteria:

  • Quality and quality again. do not save money and buy cheap products from the Middle Kingdom. They may SIMply not work or distort the sound beyond recognition.
  • Cable length. it should be enough from the connector of the computer device to the corresponding socket of the television receiver.
  • Check the presence and integrity of the connectors for this cable format on the TV and PC.

Elimination of possible problems

So, all the above connection aLGorithm is executed with scrupulous accuracy, but the sound in the TV speakers did not appear. In this case, it is necessary to use the capabilities of the computer device itself. This requires the following:

  • Carry out all the above connection steps.
  • Right-click on the speaker icon on the desktop (usually located in the lower right corner of the screen).
  • In the menu that opens, select the item “Playback devices”.
  • On the “Sound” page activate the item “Playback”.

All devices will be displayed on the screen, both their own (for example, a laptop) and connected (headphones, speakers), including a TV set in the list (you can find out by the model name or the record “Digital audio”). All that is required of you is to select it by clicking on the “Connect by default” symbol and confirm the actions with the “OK” button. When performing the listed actions, 2 problems are possible:

There is no TV name in the list. click on an empty space next to the list with the right mouse button (if the cable is working properly and is connected correctly, the name should appear) and click on the dropped device designation.

The TV receiver icon in the list is not active. you should restart the computer without disconnecting the cable and without turning off the TV.
And the last option for activating the procedure for transmitting an audio signal over a cable (performed after all the above procedures) is to check the status and operability of the controller:

  • Through the “Device Manager” you must enter the “System devices” section.
  • Find the High Definition Audio item and activate it if it is in a disabled state.

Additionally, you should open the section “Audio inputs and outputs”, activate the speaker icon and run the command to update the drivers (respectively, the device must be connected to the Internet at this moment). Sometimes, due to the lack of appropriate system updates, audio outputs (inputs) may be inactive. The program runs in automatic mode, and to start correctly, you need to carry out a complete reboot and activate the sound through the TV.

As you can see, everything is quite SIMple and straightforward. It remains only to bring the theoretical knowledge gained to life in order to use your gadgets in a variety of audio and image output formats.

Possible problems

It is clear that in some cases, in the case under consideration, some problems may also arise, let’s find out in more detail which ones, and what to do in this case.

In the event that the sound from the PC is not reproduced on the TV, you need to make some settings on the computer:

  • Just set the TV as the sound source and you’re done.
  • To do this, you need to find the “sound” icon on the computer function panel and right-click on it.
  • In the window that pops up in front of your eyes, you will need to select the function “playback device”.
  • From the list that you will see on the screen, you will need to check the box next to the item called “use by default”.
  • You need to understand that in order for the task to be completed, you need both devices to be connected to each other.

In the event that the connection to the TV is not displayed on the computer device after you have connected the HDMI cable, then the best option in this situation is to restart the computer device, and then make the settings again.

Do not forget that the format card supports sound reproduction thanks to the HDMI output type.

Today, most modern devices have a built-in function under consideration, but, as elsewhere, there are exceptions, so this fact must be borne in mind.

RJ45 connection

A router is also used here, which is configured in the same way as through a WI-FI connection. However, using this device may result in reduced speed. Therefore, it is better to give preference to an additional network card.

Setting up takes place in the same way as through WI-FI, and you need to connect through a media server.

Ways to connect audio from a computer. Connectors and their types

Often today, users make an attempt to connect the soundtrack from a computer device to a TV, because the possibilities in this case also expand, respectively, the quality characteristics of the sound increase, which clearly pleases the user. It should be noted that there is not one, but several methods of this kind of connection, each of which has its own advantages. If you decide to implement it, but do not know how, then this article will definitely interest you.

The methods of connecting sound from a PC to a TV are different, and it should be noted that each of them, as in principle and in all other cases, has its own advantages and, of course, disadvantages that everyone who decides to make such a connection should know about. Before connecting anything, you need to make sure that you have all the devices and the appropriate connectors for this process.

Despite the wide variety of modern technology, almost all, the types of connectors are identical, their variety is not so great. The main purpose of the connectors is to connect external media to various devices, including all digital equipment.

The most common connectors are the following:

  • VGA
  • DVI, etc.

Let’s take a closer look at the available methods and their variation of execution.

How to transfer sound from computer to TV

The latest versions of the HDMI cable support ARC technology, which allows transmission as. and audio signals to another device. But many users of devices with HDMI ports are faced with a problem when the sound comes only from the signaling device, for example, a laptop, but there is no sound from the receiving (TV).

Sound connection instructions

Sound may not sound if the cable is faulty or the operating system settings are incorrect. In the first case, you will have to check the cable for damage, and in the second, carry out SIMple manipulations with the computer.

The instructions for setting up the OS looks like this:

  • In the window that opens, there will be default playback devices. headphones, laptop speakers, speakers, if they were previously connected. A TV icon should appear with them. If not, then check if the TV is connected to the computer correctly. Usually, provided that an image from the screen is transmitted to the TV, the icon appears.
  • Right-click on the TV icon and in the drop-down menu select “Use as default”.
  • Click “Apply” at the bottom right of the window and then “OK”. After that, the sound should go on the TV too.
  • If the TV icon appears, but it is highlighted in gray or when you try to make this device to output sound by default, nothing happens, then just restart the laptop / computer without disconnecting the HDMI cable from the connectors. After reboot everything should be back to normal.

    Also try updating your sound card drivers using the following instructions:

      Go to Control Panel and under View, select Large Icons or Small Icons. Find “Device Manager” in the list.

    There expand the item “Audio and audio outputs” and select the speaker icon.

  • Right-click on it and select “Update drivers”.
  • The system itself will check for outdated drivers, if necessary, download and install the current version in the background. It is recommended to restart your computer after the update.
  • Additionally, you can select “Update hardware configuration”.
  • It is not difficult to connect audio on a TV that will be transmitted from another device via an HDMI cable, as it can be done in a couple of clicks. If the above instructions do not help, then it is recommended to check your computer for viruses, check the version of HDMI ports on your laptop and TV.

    Via HDMI connector

    The audio output from this connector is the most popular, as there are fewer problems and problems with it, and the sound quality remains good. This cord may be supplied with some digital devices or sold separately.

    There is no need to purchase a too expensive cord, since regardless of the price, the same materials are used in its manufacture, which do not change the sound quality.

    To connect the TV to the computer, you first need to disconnect both devices from the power, and then connect them with a cord. This connection method does not require any additional settings, it is enough to specify the HDMI output as a sound source on the TV.

    How to connect sound from computer to TV via Dvi cable?

    The second most popular method, which is used when it is impossible to connect via HDMI output. Connectors of this type are divided into three types: digital, analog and combined. However, with the transmission of sound through this connector, not everything is as SIMple as with the previous one, since everything depends on the card used in the computer, because not all of them support audio playback via DVI output.

    In the case of transferring not only audio, but also a signal to the TV, you must use a DVI-HDMI cable or connect the devices using DVI-D to HDMI adapters, and then an HDMI-HDMI cable. Such a complex connection system is due to the fact that the signal does not always pass through the DVI cable.

    The disadvantage of this method is also the complicated configuration process compared to the previous option. First, in the TV menu, you must select the DVI connector as the signal source, while the computer and TV must be connected to each other.

    What to do if no sound is output from the computer to the TV via HDMI?

    In addition to some experiments with replacing devices, cables, etc., you can apply a few more solutions that may help solve the problem with the sound output to the TV speakers.

    I also had this that after connecting the TV to the computer, there is an image, but there is no sound. This problem was almost always solved by changing the default audio output device to HDMI. The second most effective solution is to remove the sound card from the device manager (namely the HDMI device, which is for displays).

    Since the problem is very ambiguous and there can be a lot of solutions, I will be grateful if you do not pass by and share useful information in the comments. Describe a solution that helped you bring not only picture but also sound to the big screen. Or just write which solution from the article helped you. Good luck!

    Connection methods via cable

    Several methods have been developed that allow you to switch the sound from your computer to your TV. Each method has its own advantages and disadvantages. The choice of the synchronization option depends on the models of the equipment used and the availability of the necessary cables (if wired). Before starting the pairing process, you should study the technique for the presence of various ports.

    HDMI is the most widely used data transmission method. Experts recommend choosing this option due to the high sound quality. This method minimizes problems and various synchronization problems. Minus. only modern TV models are equipped with HDMI interface. They are absent on older models.

    To connect a TV receiver to a PC, you need to disconnect the equipment from the power supply and use a cable to connect it through the appropriate port. The audio will then automatically be redirected to the new hardware. No additional user settings are required. The connection process takes a few minutes.

    If your TV does not have an HDMI connector, you can use another method to transfer sound from one type of equipment to another. The use of this pairing option is also relevant for modern users.

    All existing DVI connectors can be divided into 3 categories:

    • digital;
    • analog;
    • combined.

    Some difficulties can be encountered when transmitting audio through the DVI port. Successful pairing is affected by the card model used by the PC. Only a few are equipped with DVI outputs. But if such a connector is still available, it will not be difficult to output the sound.

    This option has the advantage of maintaining optimal sound quality. As a disadvantage, the need for customization is noted, which completely disappears when using the above-described option. To redirect audio, you need to open the TV receiver menu, select a new audio source (in our case, this is the DVI port) and save the changes. During synchronization, equipment must be physically connected.

    The following method is considered obsolete, but still remains relevant. It is inferior to the previous two options in quality, but it is great for connecting a computer with an old TV.

    Typically, the required port on a home computer is occupied by the cable from the monitor. To connect the equipment without disconnecting any components of the PC, you need to use an adapter and a separate cable designed specifically for the audio signal.

    The VGA port is not designed for audio transmission. It will be possible to withdraw it only when using special devices, including the presence of a cable. The price of a cord, without which connection is impossible, is higher in comparison with other types of cables. over, this synchronization option is inferior in quality to all the above methods.

    Many owners of old TVs equipped with RCA connectors are interested in the possibility of pairing such a TV receiver model with a computer. This can be done using the tulips cable, which is familiar to many users.

    The plugs and connectors required for pairing are colored to enable correct connection. The yellow channel is needed to transmit the image, and in our case it is not used. You will need red and white connectors to redirect audio. The manufacturer decided to split the audio signal into 2 channels (right and left), providing 2 separate plugs for them.

    Next, the equipment is physically connected using an RCA cable. Connection is made by colors. The next step is hardware setup. You need to turn on the PC and change the screen resolution, taking into account the size of the TV. The TV receiver is switched to the mode.

    If everything is done correctly, the sound will come through the connected equipment. Despite the fact that this option is outdated, it will not be difficult to find and purchase a tulip cable. Available in two or three plug options.

    Wireless options

    Modern users who have been familiar with the device and the operation of digital equipment for several years make a choice in favor of wireless synchronization. This option is more convenient than wired, but there are some peculiarities that must be taken into account.

    When choosing to pair equipment with a PC via a Wi-Fi signal, you need to evaluate the capabilities of a TV receiver. The TV must be equipped with DLNA technology support. You will also need a player for various media files.

    Almost all modern TV models have everything you need to perform pairing, in this regard, the method of connecting via Wi-Fi is considered an alternative to pairing via an HDMI cable.

    There are a few settings to be made.

    • First you need to check the presence of a wireless module in the TV device. You can find the information you need in the operating instructions.
    • After that, you should configure the router to work in DHCP mode. It is recommended that you set a password during this step. It will protect the connection.
    • Turn on the TV and open the menu, you should go to the “Wireless connection”.
    • We find the desired network and connect using the set password.
    • To output a sound signal, you need to install a media server on your PC. With this program, the user opens access to files that are stored on the computer.
    • To transfer sound to new equipment (from a computer to a TV), open the media server on the PC, and select Ethernet as the source on the TV receiver.
    READ  There Is No Sound In The TV What To Do

    Despite the convenience of this method due to the absence of cables, it has disadvantages. The sound playback process significantly loads the local network, as a result of which the data transfer rate decreases.

    The most convenient methods for maintaining the quality of the transmitted signal are connections via the HDMI port and using a Wi-Fi signal. The rest of the options are recommended to be used only when the two options above are not available.

    How to switch audio from computer to TV?

    All modern digital technology is designed to be synchronized. The equipment is connected to each other to use new functions and capabilities. By pairing a computer and a TV receiver, you can significantly improve the picture and sound quality, making watching movies and listening to music more comfortable.

    Possible problems

    Pairing between your computer and your TV is fairly straightforward, especially if you use modern connection methods. However, even experienced users can face various problems. Knowing the right approach, you can quickly solve the problem yourself or find the source of the problem.

    If you don’t hear sound from your new device when using an HDMI cable, you need to designate the TV receiver as the new sound source. This is done using a PC.

    • Find the speaker-shaped icon (located on the taskbar).
    • Click on it once with the right mouse button (RMB).
    • Go to the section “Playback devices”. In the window that opens, find the name of the TV and select it using the RMB. It is necessary to mark it with the item “Use by default”.
    • Check the hardware again

    It will be useful to check the model of the card and the presence of an HDMI output on it. It will definitely be on new devices.

    We offer a list of common common problems and solutions.

    • Check the integrity of the cable used when connecting. It should be free from defects and other severe damage, however, even visual integrity cannot be guaranteed. A wire break under the braid may occur and the cord will not function.
    • When using a wired connection, remember to keep the cables free of tension. In this case, they may fall out of the connectors or be loose inside, causing interference.
    • Do not forget to periodically check and update the driver on your computer, namely on the card. This essential software is required for the device to function. Without it, the PC may not see the connected equipment. You can download the driver for free from the official website of the card manufacturer. You can also check and update the software using standard operating system tools (for advanced users).
    • Another reason that prevents synchronization is the presence of viruses on the computer. If the system fails, check with an antivirus program. Perform a full scan if necessary (the process may take a long time). Experts recommend regularly checking your PC.
    • Over time, connectors become clogged with dust, debris and oxidize. It can also cause a crash. Examine them carefully and assess the condition. You can use a regular cotton swab or soft cloth to clean the dust from the ports. For a gentle removal of oxidation, it is better to contact a service center.
    • With prolonged and frequent use, the ports begin to play. In this case, you cannot do without repair.

    Next, see how to set up computer sound on your TV.

    Possible device connection problems

    • If the sound is not reproduced, then you need to set the TV as a sound source using a computer. To do this, by right-clicking on the sound icon in the lower left part of the taskbar, select “Playback devices” from the pop-up menu. From the list you need to select your device, right-click on it and put a checkmark in front of the menu item “Use by default”.

    At the time of setting, the devices must be connected to each other. If the computer does not see the TV when the HDMI cable is turned on, then you need to restart it and repeat the setup procedure again.

    • You also need to make sure that the card supports audio playback through the HDMI output. Often all modern devices are equipped with this function. However, some of them come with a special jumper that helps to create a SPDIF out connector on the motherboard with an SPDIF in connector on the card.
    • You can solve the problem if you reinstall or update the drivers on the card.

    Connecting audio from a computer to a TV?

    Connecting audio from your computer to your TV expands your TV experience, making music or movies sound better. There are several ways to do this, they all have their pros and cons, therefore, it is necessary to give preference to one or another method taking into account the characteristics of the technique and its capabilities. Before connecting audio from a computer to a TV, you need to make sure that the devices have one of these connectors.

    How to transfer sound from computer to TV via WI-FI

    This method puts forward additional requirements for the TV. support for DLNA technology and the presence of a player for multimedia files. Modern plasma models are equipped with this function, so this connection method can be considered as an alternative to HDMI.

    Ways to connect audio from a computer. Basic connector types

    Almost all modern technology is equipped with one of these types of connectors. They are designed to connect external storage media and DVD players, as well as other digital equipment, to which the computer belongs.

    The most commonly used connector types are:

    • HDMI;
    • DVI;
    • VGA;
    • Wi-Fi;
    • RJ45;
    • RCA cable.

    VGA cable connection

    This is an outdated method that loses to the first two in terms of ease of connection and playback quality. Therefore, it is often used in outdated devices where it is impossible to connect using other cables.

    Via HDMI connector

    The audio output from this connector is the most popular, as there are fewer problems and problems with it, and the sound quality remains good. This cord may be supplied with some digital devices or sold separately.

    There is no need to purchase a too expensive cord, since regardless of the price, the same materials are used in its manufacture, which do not change the sound quality.

    To connect the TV to the computer, you first need to disconnect both devices from the power, and then connect them with a cord. This connection method does not require any additional settings, it is enough to specify the HDMI output as a sound source on the TV.

    Connection setup

    After making sure that the TV is equipped with a built-in WI-FI module, you can start setting up.

    • First, you need to configure the router so that it can work in DHCP mode.

    When setting up, it is imperative to assign a password that will protect the local network from unauthorized entry.

    • In the TV menu, you need to find the item “Wireless connection”, and then find your network and enter it with a password.
    • To transfer sound to your TV, you need to install a special program on your computer. a media server. Then, using this program, you can access files and folders containing music or movies.
    • To switch the sound from the computer, you need to open the media server, and select Ethernet as the playback source on the TV.

    RJ45 connection

    A router is also used here, which is configured in the same way as through a WI-FI connection. However, using this device may result in reduced speed. Therefore, it is better to give preference to an additional network card.

    Setting up takes place in the same way as through WI-FI, and you need to connect through a media server.
