This is the recommended solution if you are looking for a permanent way to remove audio delays on VLC’s video playback. With a few settings configurations, you can save and apply all the settings to all the videos played on the media player. Unlike using a keyboard shortcut, there’s no need for you to adjust the settings every time you watch a video manually. See the steps below to fix audio delay VLC.

  • This will launch the “General audio settings” on the right side of the window. Set the “Audio desynchronization compensation.” Put the value to “positive” if the audio lags behind the video.
  • On the other hand, set the value to “negative” if the audio is ahead of the video. For example, if the audio is 2 seconds delayed, set the settings to “+2000ms.” If the audio is 2 seconds ahead, set the value to “-2000ms.” Once done, hit the “Save” button and check if the problem is solved.
