Fixing VLC Audio Delay


Is your sound not syncing with video in the VLC player? This is always going to be annoying, and at worst, it can even totally change the video for you. Nothing impacts your enjoyment of a movie or show worse than everything just being slightly off.

Sometimes, the video might glitch, and the audio not matching the video will only last a few seconds. Often, though, the problem will go on for much longer and need you to take action to fix it. There may even be a bug whereby the audio and visuals always load desynchronized. This is incredibly annoying, especially if you can’t work out a fix.

VLC media player is popular and works on a huge number of devices, but there are some known bugs and problems that can crop up. This sync issue is one of them, and it occurs more often for Mac users. Plenty of people are looking for a solution.

How Can You Solve The Audio Delay in VLC Media Player?

If you wish to persist with the software, and try to fix the VLC player audio delay or mismatch, then there are a few things that you can try.

Relaunch VLC App

Relaunching the app sometimes fixes things. This advice is true no matter what app you are using. If there is an error, there is often a good case for turning it off and then on again. There may have simply been a problem causing the VLC audio-visual sync to go out of place during playback.

VLC application window

By closing the VLC app and reopening it, then loading the video you wish to watch again, there is a good chance that you will end up with the video working perfectly and in sync. It only takes a couple of seconds and is worth a try before you take more drastic action. It is possible that restarting the app is all that is needed.

Keyboard Shortcut, Hotkeys

Hotkeys are available to help people quickly shift the audio and not have to go into complex settings menus. A couple of keys on the keyboard can tweak the audio to move it back or forward slightly.

This is only a short-term fix for the VLC audio synchronization issues. It only works for one playback, and the next time you launch the player, you will be back to square one. However, this might not be a big deal if you only plan on watching the video once to grab some information.

Mac users can press ‘G’ to push the audio back (slow it down) or ‘F’ to bring it forward. This is a quick way to move the audio around.

The player is simply tweaking the delay by 50 milliseconds every time. You can usually make VLC sync audio in this way, at least to the point where you don’t notice any delay. When you press the hotkey, you get a quick display showing you that the player has been adjusted. 

Value-based Audio Track Synchronization

50 ms is a short timespan, but if you feel like you can still hear the desync, and would like higher precision, then you can set the synchronization value in VLC’s settings menu. However, keep in mind that the offset will not be remembered and will reset the next time you load your video.

To change the audio track synchronization:

  • Open “Window” on the Menu Bar.
  • Choose “Track Synchronization.”
  • Enter the desired audio delay in milliseconds.

To make this process easier, adjust the delay using the hotkeys at first. Once it’s close enough, use the Track Synchronization dialog to make precise changes.

VLC Sync for Every Video

If you find that each time you open the VLC app, you are finding the sound and picture out of sync, you can take more permanent action in the media player. Before taking this action, make sure you consider the fact that this will change every video, so whether you’re streaming something live or watching a video for the 50th time, the synchronization settings will remain permanently.

The “audio desynchronization compensation” is the value you’re looking for if you find that the same lag is always in place on the videos you watch. This permanently changes the way the program can synchronize audio and video and puts the same shift into place for every single video.

If you wish to move ahead with making this change, you should open the VLC player and do the following:

  • Head to the Menu bar and choose “VLC > Preferences.”
  • Click “Show All.”
  • Locate the “Audio desynchronization compensation” option in the “Audio” sub-menu.
  • Now you need to tweak the setting. Remember – you can use positive or negative values to move the audio and bring it backwards or forwards as required.
  • Continue to tweak until the video is absolutely perfect. The compensation should now be repaired.

This is a permanent fix if there is some issue making the audio and video out of sync each time you load the app. However, if different videos have different levels of lag, then you might not find this is the best solution. It can take a while to get the perfect timing to sync the audio to the video, too.
