Quicktime/OS X: No Audio For AVI Files? Solution: Perian

Posted August 1st, 2008, in: Computer Problems and Fixes| Technology

.avi files are all over the place in the BitTorrent world.

If your Mac doesn’t seem to be able to play back .avi files with sound, you’re not alone.

But the solution is simple. After a year of this, I finally found it. No longer do I need the VLC player, which was my old work-around for this problem.

Download Perian, “The swiss army knife of Quicktime components.”

Problem solved. I can finally play avi movies and hear the audio in quicktime, itunes etc.

Interestingly enough, some people are saying that AVI is actually supposed to be an obsolete format. From a mac support forum:

“AVI is merely an (outdated) container which can include a number of different codecs, not all of which can be made Mac-compatible.”

…And from some random MIT-related site, I found:

“AVI (Audio-Video Interleave) is a rather old file format that Microsoft has been trying to abandon for years in an attempt to get people to switch to their Windows Media format instead. However, the simplicity of AVI and its ubiquity and made it quite popular, so AVIs are still widely used. There are many third-party developers using AVIs, so there is a wide array of AVI codecs available.”

Magic! Thank you so much for this solution! Finally all my .avi files work again on Quicktime. I was using DivX to play them which takes so much longer to open up. Thank you so much!!

i installed perian because i’m not able to hear audio on the videos from Cosmeo (even if i save them to quicktime on my desktop. it didn’t solve the problem. is there something i have to do aside form installing perian? i went through all the readme’s and thigns, and it seems like i just install it, open it, and poof, quicktime should be fabulous. am i missing something? Thanks!

I took a look at Cosmeo. It looks to me like they’re all Flash Videos on that site. Maybe I’m missing something. They have a page for figuring out if your computer/browser is compatible:

On the other hand, if it is an AVI file you’re trying to play and you’re not getting sound, and Perian didn’t work, there’s always the VLC Player, which plays just about everything:

Another thing you might try is doing a routine permissions repair, which you should do any time your mac starts doing something weird:
