KMPlayer Audio Sync Issues on AVI Files

I updated my KMPlayer recently to version and noticed the audio would immediately go out of sync when playing .AVI files. Follow the instructions below to fix.


Step 1

Launch KMPlayer and go to preferences. F2 or Right Click > Options > Preferences.


Step 2

Then select “Source Filter.”

Step 3

Then change Normal AVI: and Damaged AVI: to say System Default.


Hit close and you should be good to go!

I know this hasn’t worked for everyone. If it doesn’t work, I would simply recommend going back to a more stable version until they get the kinks worked out. Version is very stable and doesn’t have any syncing issues with the audio. You can download the older versions here.

    It worked for me too! Very god man!

    Nice. I think it worked fine.

    If the Source Filter option does not work, you can still use Audio Resync in KMPlayer.

    This option can get rid off you lip sink issue.

    • Actually the audio resync feature wasn’t working for me. It would resync audio back up and then 5 minutes later, it would go out of sync again.

    I don’t know about the others but it worked like a charm for me:)

    my problem is with mp4 file…the audio and video not sync

    • I have seen some mp4 files that were ripped completely wrong and have really bad syncing issues.

    change your power settings to balance or performance mode.

    • We were running on a desktop when this happened. So everything for us was already defaulted to performance mode. However, I could see how this could fix the issue if you were running on a laptop. Thanks Erfan!

      Same problem here.

        It happens to me, too, but it’s really random. Some files I can seek just fine and others the sound cuts out. What’s worked so far is I take the problem files and “direct stream” encode them to MP4 and the new file works just fine.
