LG Soundbar HDMI ARC Not Working: How Its Fixed

If you have an LG soundbar and a TV that supports HDMI ARC (Audio Return Channel), you may enjoy the convenience of connecting them with a single HDMI cable. HDMI ARC allows you to send audio from your TV to your soundbar, as well as control both devices with one remote. However, sometimes you may encounter some issues with LG soundbar HDMI ARC not working properly. In this article, we will explain the possible causes of these issues and how to fix them.

LG Soundbar ARC Not Working Causes and DIY Fixes

There are many reasons why LG soundbar ARC may not be working. Here are some possible solutions:

Carefully Check The HDMI Connection

Make sure you are using the correct port on both your TV and soundbar. The port should be labeled as HDMI ARC or HDMI eARC (enhanced Audio Return Channel). Also, make sure the cable is securely plugged in and not loose or damaged. You may want to try a different cable or port to see if that solves the problem.

Examine The TV and Soundbar Settings

Check if the settings in your TV and soundbar are correct for HDMI ARC. For example, on your TV, you may need to enable HDMI CEC (Consumer Electronics Control) or Simplink (LG’s version of CEC) to allow your devices to communicate with each other. You may also need to select the right audio output or input mode on your TV or soundbar, such as PCM, Dolby Digital, or DTS. Refer to your user manuals for more details on how to adjust these settings.

Check The Firmware Updates

Sometimes, your devices may need a firmware update to support HDMI ARC properly. You can check if there are any available updates for your TV or soundbar by going to their settings menu or visiting their official websites. Follow the instructions on how to download and install the updates if there are any.

Reset Soundbar settings

If none of the above solutions work, you may want to try resetting your soundbar to its factory default settings. This may clear any glitches or errors that are preventing HDMI ARC from working. To reset your soundbar, press and hold the Volume Down button on the remote for about 5 seconds until you see “RESET” on the display. Then, reconnect your soundbar to your TV via HDMI ARC and see if that works.

Check Other HDMI Devices for more Info

If you have other devices connected to your TV via HDMI, such as a Blu-ray player, a game console, or a streaming device, they may interfere with HDMI ARC. Try disconnecting them one by one and see if that makes any difference. You may also want to check their settings and make sure they are not conflicting with HDMI ARC.

Check If there is Obstruction

Sometimes, physical obstructions such as furniture, walls, or other devices may block the signal between your TV and soundbar. Make sure there is nothing in between them that could affect the connection. You may also want to move them closer together or change their position to improve the signal quality.

Get an HDMI Splitter

If you have multiple devices that you want to connect to your TV via HDMI, but your TV only has one HDMI ARC port, you may need an HDMI splitter. This is a device that allows you to connect multiple HDMI sources to one HDMI output. However, not all HDMI splitters support HDMI ARC, so make sure you get one that does. You can find some examples of HDMI splitters that support ARC here.

Get an HDMI Switch

If you have multiple devices that you want to connect to your soundbar via HDMI, but your soundbar only has one HDMI input port, you may need an HDMI switch. This is a device that allows you to switch between different HDMI sources using a remote control or a button. However, not all HDMI switches support HDMI ARC, so make sure you get one that does. You can find some examples of HDMI switches that support ARC here.

Check other possible issues

If none of the above solutions work, there may be other possible issues that are causing LG soundbar ARC not working. For example, there may be a compatibility issue between your TV and soundbar models, or there may be a hardware defect in one of them. You may want to contact LG customer support or a professional technician for more help.

Contact Support For More Help

If you have tried everything and still can’t get LG soundbar ARC to work, you may need to contact LG customer support or a professional technician for more help. They may be able to diagnose the problem and offer a solution or a repair service. You can find the contact information for LG customer support here.

Comparing LG Soundbar HDMI ARC and Optical Connection

If you have an LG soundbar that supports both HDMI ARC and optical connection, you may wonder which one is better for connecting it to your TV. Here are some pros and cons of each option:

Pros and Cons of HDMI ARC for LG Soundbar

Some of the pros of using HDMI ARC for connecting your LG soundbar to your TV are:

  • It allows you to send high-quality audio formats such as Dolby Digital Plus, Dolby TrueHD, DTS-HD Master Audio, or Dolby Atmos from your TV to your soundbar.
  • It allows you to control both devices with one remote using HDMI CEC or Simplink.
  • It simplifies your setup by using only one cable instead of two.

Some of the cons of using HDMI ARC for connecting your LG soundbar to your TV are:

  • It may cause some issues such as no sound, no signal, or compatibility problems due to different settings, firmware, or devices.
  • It may require a firmware update or a compatibility mode to work properly.

Is Optical Audio Better Than HDMI ARC on LG Soundbar?

Optical audio is another option for connecting your LG soundbar to your TV. However, it has some limitations compared to HDMI ARC. Some of the disadvantages of using optical audio for connecting your LG soundbar to your TV are:

  • It can only send compressed audio formats such as Dolby Digital or DTS from your TV to your soundbar. It cannot send uncompressed or high-quality audio formats such as Dolby TrueHD, DTS-HD Master Audio, or Dolby Atmos.
