Why does my audio keep getting out of sync?

In general, there isn’t any specific reason why a single video is getting out of sync with its audio. It could be because you are watching a pirated movie or dubbed movie. If you are getting audio delay issues in original videos as well, this might be due to corruption inside the audio or graphic drivers. 

Assuming you are facing this issue on one or two videos, you may fix it temporarily using the workaround below. In case, this is happening on more than one or two videos, we suggest updating all your device drivers, especially graphic and audio drivers.

Fix – Audio/Video not in sync on VLC

Many a time while watching movies or listening to music on VLC, we face audio or video delay issues i.e. they just go out of sync. If you are also facing similar problems, try the below solutions, and check if any help –

1] Use Keyboard shortcuts to sync Audio and Video in VLC

If you are watching a movie and all of a sudden, the audio starts lagging behind or leads ahead. In such cases, all you require is to find whether the audio is coming after or before. 

  • Pressing the J key will slow down the subtitle that is leading on a video.
  • Similarly, use the K key to fasten the subtitle that is lagging behind.  

Note: If you are watching movies in VLC on a Macbook, use the following key shortcuts –

  • F – to slow down audio 
  • G – to fasten audio

In case your subtitle is also lagging or leading while playing a video on VLC, use the below hotkeys –

  • G – to delay subtitle 
  • H – to fasten subtitle

2] Change Audio Track Synchronization

Alternatively, you may also use the Audio Track synchronization setting to fix the audio delayed issue on VLC. The audio track synchronization value gets cleared off the moment you close the media player. Even in cases where you want to rewatch a particular video, you have to set the track synchronization value again.

Here’s how to set Audio track synchronization on VLC Media Player –

  • Open VLC and start playing a video. 
  • On the menu bar, click Tools and then Effect and Filters.
  • Go to the Synchronization tab.
  • Change the Audio track synchronization value and check if this syncs audio with the video.

Tip: If the audio is coming before the video part, put a positive value. Doing so will delay the audio. Similarly, if the audio comes very late, putting a negative entry will make the audio come in sync with the video. 

  • You have to assign many values before your video and audio come in sync with each other. 
  • After you fix the delayed audio issue, click the close button, and enjoy your play. 

3] Change VLC Audio desynchronization compensation

VLC clears off the audio track synchronization value so that you don’t face issues while watching a new video. In cases where you require a permanent solution, go to the VLC setting, and adjust the Audio desynchronization compensation. To do so, use these steps –

  • Start playing any video using VLC.
  • Go to Tools > Preferences.
  • Select Audio from the list of available options, and then mark the radio button – “All”. You may find this radio button at the bottom left corner as shown in the snapshot below –

  • This setting is by default set to “0”. 
  • Change it to positive if the audio is lagging or negative when the audio is coming ahead of its video part.
