After Mountain Lion, QuickTime player's audio skips after fast-forward

Just got mountain lion, and now when I play a video in quicktime and fast-forward, the audio (after returning to normal play speed) skips like a broken record. I click stop and then play, the skipping is still present. It only goes away if I close the video and reopen it anew.


Any ideas?


I appreciate any help!

I tried to report the issue via the website you referenced, but I am not an Apple Developer so I was unable to do so.

While you appear to be correct that is is a "developer" only reporting workflow which probably requires more immediate attention/response from Apple, it is not the only reporting vehicle. Any user can provide product feedback on any Apple product via this URL:

This feedback can be in the form of an Enhancement Request, Bug Report, Design/Ease of Use issue, Efficiency/Workflow issue, Software/Hardware Compatibility issue, Connectivity/Interoperability issue, Configurability issue, Language-Specific Bug/Issue, or "Other" issue. Simply go the to feedback page, select the product for which you wish to provide feedback, and fill out the form with your information and comments.

Same issue here. Mountain Lion. Retina MacBook Pro. After fastforwarding, the audio will continue to skip even though the video is playing at normal speed.


Thanks for the link. I just reported the bug to them as well.


[EDIT] The aduio is still out of sync if you pause it then play it again but it also seems to go back in sync if you pause it, then play it again after 5 mins or so of waiting. But waiting 5 mins is not a fix. It's still a bug.

I updated to 10.8.2, sadly still having troubles with fast-forwarding followed by stuttering audio. But I wanted to share a temporary fix.


Close the file and reopen, and that works. But that loses my spot so that was getting annoying. I found out I could go to Trim mode (command-T) and back out, and the audio would fix itself. (And not lose my spot.) (< On an individual basis. It usually breaks again sometime the next video.)


Don't know if this will work for anyone else but it's worth a shot 🙂

Sure. Happy to.

1) Pause the QuickTime player playback.

2) Just open Terminal.

3) Type "purge".

4) Wait for the prompt to re-appear. (10-20 seconds depending on how much memory it's cleaning up.) Voila!

5) Return to QuickTime and press play to continue. Audio returns to normal.


Hope this helps. Cheers!


*note: when Mountain Lion was first released, typing "purge" threw an error message about a missing library --even though "purge" was actually still working. That has been subsequently fixed. I'm running 10.8.2 on an early 2008 Intel MacbookPro w/ 6G RAM.
