Some of my AVI's won't play sound.

    When I open some of my AVI files in quicktime, they say they're missing a component, and when I click on the link, it takes me to a list on the apple site with lots of different components. The video plays fine, it's just the audio, does anyone know what I'm doing wrong, or which of these I should download?

    Rather than play it in Quicktime, use VLC. It's marvellous :cool:

    Otherwise, whenever I get a problem like this I convert the file to .mov using Visual Hub

    I've had that same problem lately. (a few times anyway) Stupid quicktime codecs.

    I know you can use VLC but goddamnit maybe I want QT to just open it properly. (QT is nice for the "trim to selection" tool and export to frames)

    Anyway, I too would love a solution to this.

    Have you guys having problems upgraded to iLife08 by chance? Ive been having some trouble with different movie files myself in QT and wondering its its related. Prior to the upgrade I never had a problem. But now Im getting some that wont play audio, some that will play audio but no video, and then some that are just kind of choppy. Yes, I too have VLC, but would prefer QT to handle everything.

    I had this same problem and believe I found the solution. In VLC on the top bar,click audio. Then tracks and put it on track 2. Thats what would happen to me it would be on track one and some of my files the sound was on track two.

    Hope it helps.

    except VLC is not the app in reference. I'd like it to work in Quicktime.

    Do you have the A52Codec Universal.dmg installed?

    Certain divx's and rips use the soundsound audio codec mpga (iirc) and this is needed.
    VLC's show file info will point out what audio codec it's needs.

    Please bear in mind that .AVI is just a wrapper that goes around all sorts of clunky, different files of varying descriptions. They are pretty notoriously low-quality and often don't work quite right in specific apps.

    It works !

    Thank you so much !

    I was having the exact same problem. Quicktime couldn't play the sound of only some AVI files.

    This fixed it !

    I found the A52 codec here :

    Now I can play all of my AVI files through FrontRow !

    Thanks again.:)
