With this in mind, I’ve looked into all of the possible reasons why your LG TV’s sound isn’t working so you can find a solution faster.

LG TV HDMI Audio Not Working may not work due to problems with the HDMI cable, the HDMI port, or the sound output settings on your device.

LG TV HDMI AUDIO/SOUND DOES NOT WORK

The sound on your LG TV may not be working because of the HDMI cable or the device connected to the HDMI cable. There is nothing wrong with your TV’s sound in this case, so other input channels and live TV should still work. Here are some possible causes if this is your experience.

Loose HDMI Cable

One of the most common problems is a loose HDMI cable, which means it hasn’t been properly plugged into either your TV or the external device. Push the cable in as far as it will go or wiggle the cable.

Output from an External Device

Another common problem is when your external device’s settings prevent the audio format 9 from playing. This is primarily for computer users. Check that your LG TV is selected in the sound output settings on your computer to home theater.

Apple Mac: Go to System Preferences > Sound > Output.

Start > Control Panel > Sounds > Playback on a PC

If your LG TV does not appear on the list, you may need to contact the computer manufacturer for assistance.

HDMI cable failure

It is possible that your HDMI cable is defective. If you want to put this to the test, connect the same cable to a different TV. If it’s still not working, the cable is most likely broken and needs to be replaced.

HDMI cables are generally available for less than $20, depending on the length required. A 6ft cable should suffice if your external device is always close to your TV, such as in the TV cabinet. Amazon has a popular and reasonably priced 6ft HDMI cable.

HDMI Port Failure

If the HDMI cable is in good condition, try plugging it into a different HDMI port on your LG TV. If the external audio device sound is working, the other HDMI port is faulty (unless the cable was not plugged in correctly).

This will necessitate either repair or replacement. An HDMI port repair will cost between $100 and $300, while a replacement will cost between $200 and $350.

LG TV DOES NOT PLAY SOUND THROUGH HDMI

It’s possible that the problem isn’t with the HDMI cable, but with the LG TV or external speakers. In this case, none of the input channels, including live TV, will have sound. Here are some possible explanations.

Volume is muffled or too low.

Sometimes the problem is as simple as the TV being muted or the volume being too low to hear. Check that you have unmuted the TV with the remote and that the volume is greater than 10.

This may appear to be a simple problem, but you are not alone. If this is your only problem, be thankful that it is so simple to resolve.

TV Sound Configuration

Another simple solution is to check the LG TV’s sound settings. If you do not have an external speaker, you must instruct the television to play the sound through the internal speaker. This can be found under the ‘Sound Out’ tab.

To change these settings, use your remote to press the ‘Home’/’Start’/’Settings’ button and then follow the steps below.

Sound Out > Audio output/Sound Settings

You must then ensure that the TV/internal speakers are selected. You could also try resetting the TV’s factory settings. This can be accomplished by pressing the ‘Home’ or ‘Menu’ button on the remote and navigating through the settings listed below for sound test.

Settings > General > Reset to Defaults > Confirm Reset > Enter the Passcode > Confirm the Reset.

‘0000’ should be the passcode. If not, you must contact LG to inquire about your specific model number.

Speakers from Outside

If you want to use external speakers, such as Bluetooth speakers, surround sound, or a sound bar, you must change the ‘Sound Out’ settings from the internal speakers to the external device. You can accomplish this by following the steps outlined above.

Check that your speaker is turned on, unmuted, and at a volume that you can hear. These may seem obvious, but it’s easy to overlook them when purchasing a new digital audio system.

Another possibility is that your speakers are not properly connected. Check that your cable is not loose and that it is functioning properly. If you have Bluetooth speakers, make sure you have correctly paired them to the TV according to the manufacturer’s instructions.

Some users have discovered that when external digital audio systems are connected to the HDMI ARC port, the sound does not work. This was resolved by activating the ‘Simplink’ feature. To use this feature, press the ‘Home’/’Start’ button on your remote and then follow the steps below.

SIMPLINK > General > Activate Firmware Bugs

If nothing seems to work to restore sound to your LG TV, there could be a bug in the firmware. LG soundbar provides constant firmware updates, so it could be as simple as updating your TV. This is also something you should do with your other devices, such as your media player or computer.

If your LG TV is already up to date, it could be a new bug that LG is unaware of. You should contact their customer service to report the problem so that they can release a new update that fixes it.

For example, some users discovered that when they used LG’s Netflix app, the sound would stop working when they switched to another app. LG recommends exiting apps properly with ‘app exit,’ but some users still experienced problems. LG was able to release an update to fix the bug after being made aware of it.
