Software Bug

LG launched software to fix this bug around July 5th, 2021. You can check the official website for more information on this bug and the software found. Since the software update has been released already, it should update automatically on your device.

So, if you are still facing this issue, it is very likely that your soundbar is not set up on a Wi-Fi network. Below is a list of instructions you can follow to set your soundbar to a Wi-Fi network. Once it is set up correctly, the update will take place automatically. 

  1. Download Google Home App from Google Play Store or Apple App Store if you do not have it already. 
  2. On the Home page, select the ‘Add’ option to add your devices to the app list. 
  3. Select ‘set up devices’.
  4. Click on ‘New Device’ to add your soundbar. If you already have added it before, you can click on ‘Works with Google’ and find it there. 
  5. After clicking on ‘New Device,’ select ‘home.’ 
  6. Select your LG Soundbar from the list of devices. 
  7. Click yes if you hear the sound. 
  8. Select the room where your soundbar is placed and then choose your Wi-Fi network.

Once you are sure your soundbar is connected to w-fi, give it some time to update. Restart your device and check if the issue persists. 

Check HDMI Cables

HDMI Cable

If the problem remains despite having done the above step, chances are the HDMI cables are causing it. This soundbar needs an HDMI port to function. Check the wires properly to make sure they are in good condition. If you see any damage, it is better to get them replaced.

You might also want to make sure the part is clean and free of dust or other impurities. You can try plugging it out and then re-plugging to make sure the connection is firm. Sometimes, you might not see any damage to the cables, but they could still cause issues due to being old.

If the wires have not been replaced for a long time, consider replacing them. Restart the device after making sure the above conditions are satisfied. 

Loading Audio Source on HDMI

This is another way you can deal with the issue since it has been told to work by many LG users. You can load an audio source on HDMI and wait until the audio format is negotiated. Once the negotiation is successful, you can revert to your regular TV apps. 

To do this, turn on the device that is connected to your AV receiver. It could be a switch or, say, your play station. Once you turn it on, you shall see Dolby, DTS, .etc logos on the AV receiver. Load the app you want to watch on the TV, for example, Youtube or Netflix. This shall make the AV receiver switch to the TV.

If the setup is correct, the ARC audio shall work typically. When you turn your TV off, the arc may or maybe break. If it breaks, perform the same method again to use it. 

If the added step is excruciating for you, you can use this method until you have a professional’s guidance.
