1. If you are audio delay when you are using the television speakers, then the first step we recommend doing is to turn off the TV and then turn it back on again to see if the audio will sync.
2. You can also try unplugging the power cord of the OLED TV from the power outlet. You then need to wait for at least 10 seconds before you plug the TV back into the power source and turn it back on.
3. If your TV speaker is still not matching the mouth movements or other actions of what is being shown on the screen, then you can try using the Match Screen and Sound function by taking the following steps:
- In the Settings menu, select Sound.
- Next, select Advanced Settings.
- In the Advanced Settings menu, select Match Screen and Sound.
- Once you get to the Match Screen and Sound, you can select TV Speaker Delay.
- Next, you can change the value of the TV Speaker Delay until the audio syncs perfectly to the content being shown on the screen of your LG A2, B2, C2 or G2.
4. If you are getting audio lag when using an external speaker, headphones or other listening devices, then you can try doing the following:
- On your television set, go to the Settings menu.
- Next, you need to head to Advanced Settings.
- From the Advanced Settings menu, scroll down and then select Match Screen and Sound.
- Finally, make sure that the Bypass feature is turned on.
- With Bypass enabled, your TV will automatically attempt to sync audio to the actions being shown on its screen.
5. We also recommend turning off any AI processing that you may be currently using as these may cause audio sync issues. In order to do so, you can take the following steps:
- Go to the Settings menu on your television set.
- In Settings, you then need to select General.
- From the General menu, you need to select AI Service.
- Finally, make sure that AI Picture Pro, AI Brightness Settings, AI Genre Selection, AI Sound Pro AI and Acoustic Tuning are all disabled if they were previously turned on.
6. If you are getting audio delay when trying to watch a video from an external media player or playing a videogame from a game console, then you need to make sure that these are connected directly to your television.
If you are using a HDMI splitter and/or connecting to another external device instead of a direct connection, then these may introduce audio lag that otherwise wouldn’t occur.
7. If you are using wireless speakers, earphones, headphones or headsets, then it should be noted that you will get more lag when compared to wired listening devices or using the built-in speakers of your television.
To potentially reduce the audio lag, you can try moving your wireless listening device closer to your television. You can also avoid having any solid objects that may block the direct line of sight between your listening device and your TV. Finally, make sure that there aren’t any other wireless devices nearby as they can cause interference.
8. If you are using set-top box, media player and/or game console, then these input devices may also have audio settings where you hopefully change the audio timing in order to get better lip sync.
9. You can also try power cycling the external input device to see if the audio delay will go away.
