I have a iMac OSX, and I've had this problem a few times, so I thought I'd see if any of you guys know how to fix this.
Sometimes when I download/rip video to my computer, the sound doesn't work. I believe what I need is the ACT-L3 codec (i am unsure of this though) - but the website that the apple website links to does not have a download for said codec.
Basically, I am just looking for whatever codec I need to download to be able to play audio on select .avi files. Any help would be greatly appreciated!
