How to Output Sound from LG TV

Why may sound drop out when connected to a TV

Loss of sound when connecting an HDMI cable to a TV is a fairly common problem, associated more with inability to handle equipment than with cable problems. The standard situation is this: this cable does not conduct sound when a laptop and a computer are connected to the TV, but it appears on primary media.

WARNING: In most of these cases, the problem is simply due to the low volume level in the device. The currently adjusted volume can be viewed in the computer’s mixer or in the TV settings. Perhaps someone accidentally turned on the “silent” mode, since these buttons are usually located on the monitor case.

output, sound

The reason may lie in the banal absence of the necessary software, in other words, drivers for the required cable or TV monitor on the donor device.

REFERENCE! Also, an error may occur due to the fact that the computer is “not ready” to transmit sound, and you need to point it to a suitable device after you have connected it manually in the properties. Read below how to get rid of these problems.

How to output audio to a monitor via HDMI

One of the problems that can be encountered when connecting a laptop to a TV via an HDMI cable is the lack of sound on the TV (i.e. it is played on the laptop or computer speakers, but not on the TV). Usually, this problem is easily solved and further in the instructions. possible reasons that there is no sound via HDMI and how to fix them in Windows 10, 8 (8.1) and Windows 7. See also: How to connect a laptop to a TV, Poor image quality via HDMI.

Note: in some cases (and not very rarely), all the steps described below to solve the problem are not needed, but the whole point is in the sound reduced to zero (in the player in the OS or on the TV itself) or accidentally pressed (perhaps by a child) the Mute button on the TV remote or receiver, if used. Check these points, especially if everything worked fine yesterday. If, when diagnosing an HDMI audio device, you see a message that this device is already in use by another application, see a separate guide for this issue here: This device is already in use by another application when outputting audio via HDMI.

Additional Information

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 input.

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.
Any ideas?

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, it may be more likely in Windows, but where?

there was a problem when connecting PC to TV via HDMI. the sound was coming through the PC. And then it turned out that the administrator’s 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)

Updated all drivers, the picture is on HDMI, but the TV is not detected in 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 sound. We tried to install them from the Acer website?

Yes, I put them exactly, 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.

good day.
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 the problem in Windows (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 item 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 I take a screenshot from “Sound, Game and Video Devices” in Device Manager and Playlist? 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 mowing line for audio transmission. There is a common line for control signals, along which sound is also transmitted. Therefore, if the 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-out, but only a DVI-HDMI cable was at hand. Although there certainly 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 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). From ideas, except that the output of sound from the integrated HDMI, if available, but, again, here it would be an experiment to conduct.

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

Are there 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 ten/

Hello. I have a laptop connected via an av receiver to a TV via HDMI, after I set 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.

There is no sound on the TV set when the computer is connected via HDMI

The HDMI standard allows you to effortlessly display image and sound from a laptop or computer to an external monitor, in other words, a TV set. To convey the picture and sound, it is enough to connect the computer to the device via a cable. However, just like with any other standard of data transfer, obstacles occur with HDMI, including due to incorrect OS options. One of the most common mistakes that users have to deal with is the lack of sound on the TV set when a computer is connected to it via HDMI. This problem can be corrected by several methods, the presence of which will be discussed below.

Be careful: Before proceeding with the tips below, make sure that the lack of sound on the TV when connecting a computer to it via HDMI is not related to the options of the TV itself. Often the reason is quite common. the sound of the TV set is reduced to zero or the “Silence Mode” (Mute) is turned on.

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.

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’s Speakers or headphones, but NV is also listed, these three steps are likely to be enough to fix 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.

Installing Drivers for HDMI Audio

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

To check if this is the case, go to the Windows Device Manager (in all OS versions, you can press the WinR keys on your keyboard and enter devmgmt.msc, and in Windows 10 also from the right-click menu on the Start button) and open the section “Sound, game and video devices”. Further steps:

  • Just in case, enable the display of hidden devices in the device manager (in the “View” menu item).
  • First of all, pay attention to the number of sound devices: if this is the only audio card, then, apparently, drivers for sound via HDMI are really not installed (more on this later). It is also possible that the HDMI device (usually has these letters in the name, or the manufacturer of the video card chip) is present, but disabled. In this case, right-click on it and select “Engage”.

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

    Download the drivers for your video card from the official AMD, NV website Note: if for one reason or another the drivers are not installed, it may be due to some kind of malfunction of the current drivers (and the sound problem is explained by the same). In this situation, you can try to completely remove the video card drivers and then reinstall them.

Choosing the correct playback device

When connecting to a PC via HDMI an external device for outputting information. a TV set or a monitor, the OS of the Operating System should automatically find that the sound will be broadcast through the connected source. If this did not work out for one reason or another, the user must, without the help of others, assign TV sets as a sound playing device. For this purpose, you:

  • In the lower right corner of the screen, click on the speaker icon (“Digital Audio”) with the right mouse button and select “Playback Devices” in the window that opens;
  • A window with options for playback devices will open, in which you need to select a TV set (or another device from which sound should be output) and right-click on it. In the pop-up menu, click Set as default;

An HDMI cable is a digital device interconnect for high quality, copy-protected multimedia transmission. Since 2002, this device has evolved to this day, improving its bandwidth and adding support for new displays. Current version at the time of 2019: HDMI 2.1, supports all resolutions up to and including 10K100. What to do if sound is lost after connecting through a cable to the monitor?

How to get rid of the problem

The problem of no sound when connected with an HDMI cable is not as difficult as it sounds. For this you need:

Simple columns

It is possible to directly connect simple computer speakers to any TV device equipped with a TRS 3.5 mm jack.

They also require additional power. sockets. Before connecting speakers to an LG or Samsung TV, you need to make sure that the device has the appropriate outputs on the panel. A sound amplifier and volume control system will help you achieve decent sound.

Types of acoustics

Speakers for Samsung TV and other TV models are divided into two main groups in terms of technical characteristics: active and passive. The first are equipped with a built-in amplifier as standard and are powered directly from the mains. They do not require the help of additional devices. Typically, this type of acoustics is most often found in computer speakers.

Connection takes place through a standard Mini Jack connector. Active TV speakers are connected to the device using round 3.5 mm inputs. If the TV is not equipped with such a connector, then a special tulip adapter is used.

Passive acoustics, or subwoofers, do not have a sound amplifier, which changes the connection algorithm. It must first be connected to an amplifying device, then into one of the connectors on the TV panel.

IMPORTANT! If the polarity is not respected, the sound quality will be impaired.

Composite stereo system

The equipment has an almost perfect sound quality. Consists of the following elements: powerful speakers with a built-in amplifier, passive acoustics, and a subwoofer that decomposes sound into separate channels. Taken together, the composite stereo system will provide comfortable listening not only to musical compositions, but also surround realistic sound when watching a movie.

The stereo system is connected to a Samsung TV or other brands using the tulip connector. RCA or TRS adapters are also used. The sound from the TV is output directly to the speakers of the active group, so you need to use the recommended wires and cables.

Used types of cables

Connecting your home theater to your TV requires good quality dedicated cables. Poor quality wires tend to distort the audio signal.

In addition, there are several types of cables for connecting the loudspeaker to the TV:

  • Scart. a wire of a specific length that connects exclusively to certain types of connectors.
  • 3.5 mm Jack adapter. allows you to stably connect a device with a 2RCA output and an amplifier with a 3.5 standard jack.
  • To achieve high quality sound, connect a SCART-3.5 Jk Ph 3 m cable. Provided that the TV has a corresponding output and the external device has a 2RCA audio input.

Many users ask if it is possible to connect third-party speakers to a television device. This does not require any special skills or experience. The connection process only requires the presence of the necessary connectors and high-quality cables.

Many TVs are not equipped with the highest quality speaker system. When watching movies or TV programs, there is little sound from the built-in speakers. To make it more spacious and loud, you can connect any other sound amplifier to it. There are several options for how to output the sound from the TV to the speakers.


Many owners of computer monoblocks ask themselves the question: how to connect the candy bar to the TV? This process is simple, just connect your computer to TV via HDMI or USB cable. In the settings you need to select the input source.

It’s a little more difficult to set up the sound so that it is output from the TV speakers. To do this, go to the sound settings on your computer and select the default HDMI output. If nothing has changed, in the “Supported formats” tab you should adjust the sound frequency, which should be equal to 48 kHz.

Types of inputs and connectors

For sound output, all TVs are equipped with special inputs and connectors that allow you to connect third-party speakers. Before connecting a speaker system, you need to determine which outputs on the TV are provided.

Special purpose connectors (SCART, RCA). They connect devices without a built-in amplifier.

Digital connector (HDMI ARC). The input allows you to connect modern speaker systems to your TV, as well as amplified speakers and home theater systems with the ability to reproduce truly high-quality sound. Not all television devices are equipped with such an input, but only the newest and most expensive ones.

With HDMI input, the user can enjoy great sound through the transmission of a high definition digital signal. Not to be confused with normal HDMI input.

Headset jack and line-in. Used if the TV has no dedicated inputs. Connection is carried out by adapters. tulips.
To determine how easy it is to connect the amplifier to a TV, you need to inspect the rear panel of the device for the necessary connectors.

How to display picture or video from phone to LG TV

Modern gadgets and home appliances have long become complementary devices due to their ability to connect to the Internet and synchronize. And this is very convenient, as it allows you to expand the functionality and make the use easier and more convenient. For example, you can control your LG Smart TV with your smartphone (turning it into a remote control) or display images and videos from your smartphone on your TV screen.

What is it for? Pros of connecting a smartphone to an LG TV:

Smartphone syncing has many benefits. And here are the main ones:

  • You can watch photos and videos from the “Gallery” of your smartphone on a large TV screen in high quality.
  • You can play your favorite mobile games by displaying the image on the TV, as well as use various applications (for example, sports applications, applications for learning a foreign language, etc.).
  • It is very convenient to browse various sites, as well as read documents and view presentations.

How to connect a smartphone to an LG TV: step by step instructions

Displaying images and videos from a smartphone to an LG TV is possible in several ways, both using a cable and using wireless networks.

Screen Share is a program specially designed to synchronize your phone and LG Smart TV and watch content on the big screen. The transfer of images and videos is carried out using

Miracast standard (Wi-Fi Direct technology). The connection can be made with 100% probability if you have an LG TV and a smartphone. Option may not be supported with smartphones from other manufacturers.

In order to start the synchronization process, you need:

  • Press the Home button on your LG TV remote control.
  • Find and enable Screen Share app.
  • Make sure that the smartphone has Android operating system firmware higher than 4.2 version.
  • Activate Miracast mode (in some cases, it may be called AllShare Cast). If your smartphone does not have this option, you will need to download Miracast app on google play.
  • In the list of devices available for synchronization, select your TV and connect, following the instructions on the screen.

Important: manufacturers recommend using the phone in horizontal mode and block the change of screen positions so that the picture on the TV screen is not displayed rotated by 90 °.

Owners of non-LG smartphones can try to display images and videos from the phone to the TV using the Wi-Fi Direct function. This is possible if your LG TV is a modern model and supports Wi-Fi.

To sync your smartphone and LG TV via Wi-Fi Direct:

  • Make sure your smartphone has Android operating system with firmware higher than 4.0.
  • In the “Settings” select the item “Wireless networks”, then the item Wi-Fi.
  • Click on the three vertical dots in the upper right corner. In the menu that opens, select Wi-Fi Direct.
  • If you did not find this option, click on the item “Advanced settings”.
  • Turn on the TV using the remote control and enter the main menu.
  • Select the “Network” item, and in it the Wi-Fi Direct section.
  • In the list of devices available for synchronization that opens, select the name of your smartphone.
  • A connection request will appear on the phone itself, confirm it by following the instructions.

Connecting a smartphone to an LG TV via HDMI is possible if the phone is equipped with a mini HDMI interface; in other cases, you will need to additionally purchase a special adapter.

  • Insert one end of the HDMI cable into the back of your TV and the other into your phone port.
  • Go to the “Main Menu” of the TV and select the “Signal Source” section / Press the Input button.
  • Select the HDMI source that the smartphone is connected to as the source. The connector number can be seen on the back of the TV, but in the vast majority of cases it is the only one active.

In this way, you can display images and videos on LG TV from almost any smartphone: LG, Samsung, Huavei, Lenovo. In order to sync iPhone, you need a special Lightning to HDMI adapter.

Also, different models of smartphones can be connected to an LG TV using different connectors. For example, a number of LG phone models (including the LG 2X) are equipped with a dedicated Micro HDMI port or the more modern USB Type-C port. Also, a number of smartphones of democratic models support the MHL standard (Mobil High Definition Link), with the help of which the signal comes directly from the data transfer and Micro-USB charging port. MHL analog. SlimPort standard, implemented in many LG smartphones, allowing video transmission in 1080p resolution.

All of these methods are suitable for older models of smartphones. For newer models, we recommend that you prefer Honor wireless data transmission methods.

How to connect speakers to your LG TV

Modern LG TVs boast high-quality sound. Nevertheless, many equipment owners want to further improve the audio system by connecting speakers to the TV. This allows you to enjoy the highest quality surround sound.

Before you start connecting the speakers, you need to clarify what audio jacks your LG TV model is equipped with. The most common are digital HDMI, line-in (MiniJack) or dedicated speaker SCART or RCA.

LG TV models with Smart-TV have the ability to connect wireless speakers via Bluetooth.

HDMI. Found in most modern TVs and home theaters. Allows you to transfer information without loss of quality.

If you are going to connect a powerful audio center with built-in amplifiers to your TV, it is recommended to use HDMI connectors.

MiniJack, SCART (hairbrush) and RCA (tulip) are not designed for high-power audio systems. When using these connectors, you need to be especially careful, since if you connect speakers with a more permissible power to the TV, there is a risk of damage or even damage to the equipment.

The second thing to look out for is the speakers themselves. Acoustic systems are active and passive, and the connection method depends on their type.

Active speaker system assumes the presence of a built-in amplifier and is connected to the mains for power supply. In the overwhelming majority of cases, such speakers are connected to the TV using 3.5 mm inputs, designated MiniJack or TRS. In the event that your LG TV does not provide such connectors, you can solve the problems by purchasing an additional adapter “MiniJack / RCA”.

Passive speaker system is not equipped with an amplifier, it must be purchased separately and the speakers must be connected first to it, and only then through the amplifier to the TV. In this case, there is a possibility that the sound quality will not be optimal.

Here’s what to look for when choosing an amplifier:

  • Its power should not be more than a third higher than the power of the speakers. (Carefully read the User’s Guide for the speakers, this information is sure to be there).
  • The impedance of the amplifier and speakers must be equal.
  • The wire with which the amplifier will be connected to the TV is very important. Experts recommend not to use a cord with a cross section of less than 2 mm.

How to connect speakers to a TV using wires: step by step instructions

How to connect wireless speakers to your TV: step by step instructions

  • Turn on the TV using the remote.
  • In the “Menu” find the Bluetooth section and make sure that this option is active.
  • In the list of available devices, find the Bluetooth speaker you want to connect.
  • Sync your devices.

After you have successfully connected the speakers to your LG TV, you need to complete the process by adjusting the sound settings on the TV itself.

  • In the menu, select the item “Home” (Icon “Home”).
  • Go to the section “Settings” (Icon “Gear”).
  • In the upper right corner, find the icon with three vertical dots, and in it the “Sound” section.
  • In the subsection “Audio Out” select “Audio Out (Optical / HDMI ARC)”.
  • Activate SIMPLINK mode.

If you are using a speaker that supports LG Sound Sync:

  • In the menu, select the item “Home” (Icon “Home”).
  • Go to the section “Settings” (Icon “Gear”).
  • In the upper right corner, find the icon with three vertical dots, and in it the “Sound” section.
  • In the subsection “Audio Out” select “LG Sound Sync (Optics)”.

If you are connecting an audio system that supports LG Sound Sync using Bluetooth, select “LG Sound Sync (Wireless)” in the settings.
