If the sound does not match the video you are watching, it may take some time before you notice it. But once you have done so, it is impossible to ignore it and you will want to find a solution immediately.

You may have similar video synchronization problems under Windows. However, diagnosing the cause of the problem is a process that is relatively similar to that of your television and audio-visual equipment.

Here’s the bad news: There are a lot of things that can cause lip synchronization problems, but we hope the councils here will isolate the problem and hopefully fix it for free.

Check your player/browser software

If something does not work as expected in a browser, the first reaction is usually to try another one. I did this just to find out that this audio/video synchronization problem was occurring in all (large) browsers. I tested the latest versions of Chrome, Firefox, Internet Explorer and Edge. I also tested the Netflix Windows application. They were all affected in the same way.

Try to play another TV show or film.

Sometimes, audio and video on YouTube are out of sync because the content you are playing is incorrect. So you can try watching another TV show or movie to see if the problem really exists.

If the other content is working correctly, you can report any defective video content to YouTube (simply click on your profile image > Send feedback).
If audio and video are still not synchronized with other TV shows or movies, continue with correction 2.

Disable HPET in BIOS

High Precision Event Timer is simply a hardware timer that is used in PCs. It offers more accuracy and resolution in interrupt generation. Users have reported that disabling this timer in the BIOS works wonders for audio and video problems outside of synchronization and they magically disappear!
