However, if your video is alright but the audio turns out to be faster or lags behind the video during playback on a media player, TV, etc., you should try the following fixes:

Manually adjust the audio delay in the video player. If you’re using apps like VLC, you can adjust the audio delay through shortcuts like “K” for increasing delay and “J” for decreasing delay.
If you’re connecting an external device to your TV to watch a video, make sure the video and audio cables go in the right inputs so that the video and audio data can be transmitted seamlessly.
You can also try a different audio output to test if the audio out-of-sync problem goes away.
