• How to make hdmi transmit sound. Ways to connect sound from a computer to a TV

    For movie lovers, modern technologies provide ample opportunities to watch their favorite films comfortably. Yes, you can use a computer monitor for this purpose. However, if you have a modern, widescreen or plasma TV, then the temptation to turn it into an additional monitor will be great. Moreover, this task is quite feasible.

    Monitor and TV: advantages and capabilities

    The computer and TV are connected using a cable specifically designed for this purpose. This will allow you not only to get more pleasure from entertainment (cinema, games, the Internet), but also to work. The screen of a television receiver will become a “lifesaver” for owners of compact electronic devices: tablets, netbooks. Two high-tech devices connected together will allow, for example, viewing movies in HD or Blu-Ray quality, photographs, slides, and surfing the Internet. However, technical glitches may occur during connection. One of the most common and frequent problems is no sound on a TV connected via an HDMI cable. Let's consider options on how to cope with the task.

    Connectors and cable

    Before connecting, both devices must be turned off and de-energized. This is done to comply with safety regulations. The computer and TV have almost similar sockets designed for an HDMI cable, and they are located on the back wall of each device. On a PC, the cord is inserted directly into the video card; there are other options. For example, it can be plugged directly into the motherboard, and the connector is located next to the USB ports. The cable can have different lengths. There are identical connectors at both ends. When purchasing, you can choose a not very expensive one, made in China. However, if you are going to run large files and watch high-quality videos (for example, in 3D format), you will need a more expensive and high-quality cable. 1.4 or higher will do. There may be some difficulties when connecting. Before moving on to the problem of no sound on the TV via an HDMI cable, let’s consider another important issue: 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 cord sockets are located on the receiving device. For a TV that hangs on the wall, purchase a cable with a plug that is at an angle of 90°. If there are not enough ports, then an adapter will be required. The switcher will help you connect several devices through one port.

    Image Adjustment

    Before setting up, you need to adjust the image on the TV screen. First the PC and TV are connected and then HDMI. The message “Cable not connected” or “Weak signal” will appear on the screen. Additional settings are available via the remote control. On it you need to click the “Source” button and determine the device transmitting 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" the optimal resolution is set on the screen. Sometimes, when setting up a connection between two devices, you need to adjust the incoming sound to the TV via an HDMI cable. It must be taken into account that both video and audio signals are received through it. Therefore, setup failures are possible.

    Sound settings

    After completing all the steps described above, you can display the image from your computer to your TV. However, connection sometimes fails. The problem of how to connect audio via HDMI may arise if the drivers for the video card are not installed (as a rule, they are installed from the disk that is purchased with the computer). To check, you should look in the "Device Manager" in the "Control Panel". There you need to select “Sound, game and video devices” with the cursor. In the list, you need to click on the line indicating support for HD audio. When the TV is connected to the computer, the device will change its status to “Ready”. You need to right-click on it and select “Set as default” from the drop-down menu.

    Other connection errors

    When adjusting the image, the optimal resolution is set, which corresponds to the characteristics of your TV model. Now you have a wonderful picture on the screen, but the issue that there is no sound on the TV via HDMI may not lose its urgency. How can it be solved? Use your mouse cursor to click on the “Start” button and select “Control Panel” from the menu. In your computer settings settings, go to Hardware and Sound, then click Sound. If your computer does not have it, then you need to click on an empty space. Select "Show connected devices" or "Disconnected devices" from the drop-down menu. In the window you need to select the name of the TV brand. Now you should turn it on and turn off unnecessary devices (that is, the computer). For the last operation, you will need to right-click on the button labeled Realtek and select “Off” in the menu that appears. We will do the same with “Speakers”. If there is no sound on the TV via HDMI, just follow all the steps described above and then, of course, you will be able to enjoy watching the video in full.

    One of the problems that you may encounter when connecting a laptop to a TV via an HDMI cable is the lack of sound on the TV (that is, it plays on the laptop or computer speakers, but not on the TV).

    Note: in some cases (and not very rarely), all the steps described below to solve the problem are not necessary, and the whole issue is the sound reduced to zero (in the player in the OS or on the TV itself) or the Mute button accidentally pressed (possibly by a child) on the TV or receiver remote control, if used. Check these points, especially if everything was working properly yesterday.

    Setting up Windows playback devices

    Typically, when you connect a TV or separate monitor via HDMI to your laptop in Windows 10, 8 or Windows 7, audio automatically starts playing on it. However, there are exceptions when the playback device does not change automatically and remains the same. Here it is worth trying to check whether it is possible to manually select what the audio will be played on.

    Most likely, these three steps will be enough to solve the problem. However, it may turn out that there is nothing similar to HDMI Audio in the list of playback devices (even if you right-click on an empty spot in the list and turn on the display of hidden and disabled devices), then the following solutions to the problem may help.

    Installing drivers for HDMI audio

    It is possible that you do not have drivers installed for audio output via HDMI, although the video card drivers are installed (this could happen if, when installing the drivers, you manually specified which components needed to be installed).

    To check if this is your case, go to the Windows Device Manager (in all versions of the OS, you can do this by pressing the Win + R keys on the keyboard and entering devmgmt.msc, and in Windows 10 also from the right-click menu on the “Start” button) and open the “Sound, game and video devices” section. Next steps:

    If only your sound card is in the list, then the solution to the problem will be as follows:

    Note: If for one reason or another the drivers do not install, it may be due to some kind of glitch in the current drivers (and the sound problem is explained by the same thing). In this situation, you can try to completely remove the video card drivers and then install them again.

    If the sound from the laptop via HDMI still does not play on the TV

    If both methods do not help, and the required item is precisely 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 audio will be transmitted through the same cable, but from a different device, not from your current laptop or computer.
    • If you use an HDMI adapter or adapter to connect via HDMI, the sound may not work. If you use VGA or DVI on HDMI, then definitely not. If DisplayPort is HDMI, then it should work, but on some adapters there is actually no sound.

    I hope you managed to solve the problem, but if not, describe in detail what and how happens on your laptop or computer when you try to follow the steps from the manual. Perhaps I can help you.

    Additional information

    The software that comes with your graphics card drivers may also have its own HDMI audio output settings for supported displays.

    And although this rarely helps, look into the NVIDIA Control Panel (located in the Windows Control Panel), AMD Catalyst or Intel HD Graphics settings.

    Many users connect their computer to the TV because it is convenient and the image is of better quality. But after they turn it on, they discover that there is no sound on the TV. Then the question immediately arises. What did I do wrong, that there is no sound and how can I generally set up the sound via HDMI on my TV so that it works.

    After you decide to watch a movie on the Internet by connecting your computer to the TV, you will need: TV, computer, HDMI cable. The devices connect directly to each other. On TV, select HDMI and you're done. You get wonderful sound effect and high picture quality. In the case when it is connected correctly, but the TV is turned on and does not speak, then something has been done wrong.

    Sound not working via HDMI? This is a problem that any user who tries to synchronize two equipment may encounter. Before you resolve the issue of setting up voice playback, you need to at least find out the reason why this is happening. Most often, in automatic mode, after connecting, the sound does not play on the TV and then you need to adjust the sound. This is done as follows:

    • on the “bell” icon, you need to right-click and in the window that appears, select the “Playback devices” option;
    • the window that will open in front of you will display the transmitted signals, including the desired picture from the TV;
    • after that, select the “bell” from the TV and configure the “Use as default” item.

    Having completed these manipulations, the sound when connecting a computer will begin to be transmitted through the television device.

    If you opened the settings and did not find the icons from the second device there, how to configure it in this case. If there is no sound via HDMI on the TV and the icon that is responsible for this, you can try restarting the computer. And most likely everything will be fine right away.

    If the audio signal does not sound and nothing works during setup, then you just need to download the necessary drivers on the Internet and you can use it.

    How to connect correctly so that everything works

    There should be no problems in this matter. How to output sound? In order for a TV to transmit audio, it must have the Sound over HDMI protocol installed. But the fact is, even all new TVs have this feature. Then you will need a regular cable that needs to be connected to the Audio in output. And the device that transmits sound must have an Audio Out connection. After the connection is made, you will receive a sound when connected.

    Please note: if you yourself cannot figure out what is required for a beautiful sound, then it is better to have it all done by a professional. It will really make any device sound.

    Setup instructions

    After you have connected all the necessary wires and cables, pay attention to the fact that a picture should appear on the screen. If it is there, it means you connected it correctly. But suddenly you discovered that there was no volume. So how can you make it appear? The user immediately has a standard question: why is there no high-quality sound via HDMI on his TV?

    So, how to connect sound:

    • First, we check whether everything is on the equipment. To do this, go to the computer menu and click the “Start” button;
    • In the selected menu, click on Control Panel;
    • Next is a panel for adjusting the sound. If you can't find the icons you need, you can simply enter the computer search and enter the word sound.
    • After the procedure is completed, 4 bookmarks will open in front of you. You need to select "Play". If an HDMI cable is used for connection, then there will be a green check mark on this panel in front of the speaker. In this case, you need to change the settings and select the “Default” item.
    • Save accordingly and immediately hear what you wanted on your TV.

    Even after connecting the HDMI cable there is no sound on your TV, then you can use the instructions that came with it. This may be due to the fact that in the TV menu there are hidden settings that need to be activated. Couldn't cope on your own? Then it’s easier to turn to a specialist who knows the tricks of the trade. He will quickly help you deal with the problem that has arisen.

    Many users, not wanting to watch movies or TV shows on a small monitor, connect a laptop to a TV panel from LG, Samsung, Sony or another brand to display the image on a large screen. However, when connecting equipment using most cables, only a picture is sent to the display, whereas when using HDMI, not only video, but also an audio signal can be transmitted to the TV receiver. However, sometimes after connecting the devices, you find that there is no sound on HDMI on the TV. Such a malfunction can occur for a number of reasons, and in order to eliminate it, you must first diagnose the equipment and the configured connection.

    Diagnosing and fixing the problem

    If the audio signal from the PC does not come through the HDMI cable, to correct the error and output sound to the TV panel, the user needs check connection for all possible errors. The problem may lie in the settings of the TV receiver or PC, an incorrectly selected playback source, missing or outdated drivers, etc.

    Checking volume levels

    If there is no sound coming from the TV's speakers, you need to check whether the volume on both devices is turned off. This can be done on TV using the remote control or control keys, located on the body.

    On PC you will need click on the speaker icon in the tray(lower right corner on the monitor) and make sure the slider is set to maximum. Next, you need to call up the context menu and go to “Volume Mixer”. Here you need to make sure that the sound is turned on and set to maximum for all running applications and devices.

    Note! You can also check the volume level on a PC or laptop using the function keys. To do this, first press the “FN” button, and then press the volume up (usually one of the arrow keys or the F1-F12 buttons). After pressing, the user will see a slider with the volume level in the upper right corner of the screen and will be able to increase it if necessary.

    Hardware problems

    A problem with the cable or one of the devices is also a common reason why a PC won't transmit audio to the TV via HDMI. If the TV speakers are working properly (sound appears when you turn on TV channels), you need to check the functionality of the connector. To do this, switch the cable to another port. If the problem persists, you need to check the connector on your laptop or PC by connecting other equipment to it.

    If the connectors are in order, then proceed check cable functionality. To do this, you need to connect a DVD player or digital receiver to your TV through it. This technique does not require additional setup, so the user will immediately see the picture on the screen and hear the sound in the TV speakers if the cable is working properly.

    Very often, cheap Chinese HDMI cables that users buy in order to save money turn out to be faulty. They either cannot immediately reproduce the transmitted content, or the image (or sound) regularly disappears. To avoid such problems, you should buy reliable branded cables.

    Important! If the sound was working properly, but suddenly disappeared, this indicates that the cable may have been broken or damaged by pets. You need to carefully inspect it for external damage.

    Transferring sound from a PC to a TV panel will be an impossible task when using some adapters. So, if DVI-HDMI or VGA-HDMI were used when connecting the computer to the TV receiver, the audio signal will not pass through. A similar problem is also possible when using inexpensive DisplayPort-HDMI adapters, which also do not have the technical capabilities to transmit sound.

    Selecting the playback source

    When you connect an external audio device to your PC, Windows automatically detects the new hardware and transfers audio to it. In some cases this does not happen and the user needs to manually set audio signal transmission to connected equipment. To do this, click on the speaker icon in the tray and select “Playback devices”.

    Note! On a Windows 10 PC, you need to select “Sounds”, then “Playback”.

    A window will appear in front of the user with all available audio output equipment. You need to find the TV icon and set it as default device. As a result, sound should appear in the speakers of the television receiver.

    TV Display Settings

    If the television panel does not appear in the list of devices for sound output, you need to right-click in an empty space of the window and set labels to reflect disconnected and disabled devices. As a result, the TV should appear in the list of equipment. If this does not happen, you need to restart the PC with the television panel connected. After the computer starts again, you should re-open the playback devices tab. The TV should now be selectable. If after rebooting the PC still does not see the connected TV receiver, you need to check whether the drivers for the equipment are installed.

    Driver problem

    Another popular problem, as a result of which sound from a laptop or PC is not output to the speakers of the TV receiver, is uninstalled hardware drivers. To verify this, you need to open the “Device Manager” (for Windows 8 and 10 – through the context menu of the “Start” button, for Windows 7 – through the context menu of the “My Computer” icon).

    Advice! On any version of the OS, including Windows XP, you can use the “Win+R” key combination to open the “Run” command and enter “devmgmt.msc”.

    In Device Manager, you need to open the “View” section, and then select the display of hidden devices in the drop-down list. Next, open “Sound, game and video devices”. In addition to the audio card, the list should display one of the devices such as NVidia High Definition Audio, AMD High Definition Audio or another, with the name HDMI included - this is the component used to output audio via HDMI. If it is disabled, need to be turned on it through the context menu.

    If the required component is not in the list of audio devices, you need to install drivers so that the required utility is detected by the computer and starts working. To do this, go to the website of the video card manufacturer and, in accordance with the model, download the latest versions of drivers.

    Note! Driver installation should be done manually. For example, for GeForce graphics cards manufactured by NVidia, during installation you need to make sure that the “HD Audio Driver” is present, which is responsible for transmitting the audio signal via HDMI. On video cards from other manufacturers, this driver is called differently.

    However, if the drivers are not installed for any reason, you must completely remove the video card software and the hardware itself from the system and then install it again. To download these auxiliary utilities, the user will need an Internet connection, which can be configured using the services of providers such as Rostelecom, MTS, TTK and others.

    NVIDIA controller

    If a graphics adapter from NVidia is installed on a laptop or PC, in order to transmit the audio signal to the TV, the user will need access the built-in audio controller. To work with it, you need to launch the video player through which you usually watch movies or TV series, and in the sound settings, enable Nvidia High Definition Audio as the default device.

    Other faults

    Usually, along with sound drivers, software is installed on the computer, which has its own utilities for outputting sound via HDMI. Such programs include Intel HD Graphics, AMD Catalyst, NVidia Control Panel, etc. In rare cases, this circumstance may cause the absence of an audio signal on the TV receiver when connected via HDMI. To correct the situation, you need to open such a utility and configure the sound settings correctly.

    Features of settings on different versions of Windows

    Setting up sound on Windows OS of different versions is the same, but it is possible differences in the locations of the required sections. For example, on Windows 7, “Playback devices” are available from the context menu of the speaker tray icon. And to open the same tab on Windows 8 or 10, you must first click on “Sounds” and only then on the “Playback” tab. The main nuances of the location of certain sections were discussed in the relevant paragraphs of the above material.

    So, if the user decides to connect a computer via HDMI to his Philips, Toshiba, Panasonic or other brand of TV, but after connecting he finds that only the image is transmitted and the sound does not work, then he first needs to diagnose possible software problems, and then identify problems in cable or connectors. Lastly, you should check the equipment itself for serviceability, and if a breakdown is detected, contact professional technicians at the service center, excluding repairs on your own, so as not to aggravate the problem.
