10 Use appropriate and virus-free audio/video codecs.

Both incompatible codecs and damaged files have the potential to cause an audio delay while playing. As a direct result of this, the media player is unable to correctly read the file information or calculate the time length of the corrupted portion. You can either fix the audio sync error by changing the video and audio codec so that it is compatible with each other or by cutting off the broken segment.

 

It's possible that the problem lies within the media player itself, or it could be an infection brought on by the application. Therefore, the first thing you can do when you are unable to play a video due to an unsupported audio codec is to switch the media player or use a different device to play the video. In the event that none of these workarounds are successful, you can alter the settings of both the Windows Media Player and the VLC Player to automatically download the appropriate codecs.

 

If this does not work try using the software Wondershare Repair to fix the problem.

Therefore, reopening the streaming video and any other videos on YouTube after restarting the browser might be enough to fix the sync issue.

21 Try Changing Web Browser

 If you are experiencing lag between the video and the audio while using one browser to open streaming or YouTube videos, then you should try switching to a different browser. In the event that you are having problems with Firefox, you could try switching to another web browser such as Google Chrome, Opera, or Brave.

22 Check Streaming Services

Streaming Services like Youtube, Netflix, and Amazon Prime have a lot of things happening behind the scenes, and if some of the services that are interlinked fail, it could cause sync problems. You have no choice but to wait until the streaming services fix the problem, as this is the only thing you can do.
