a52 codec problem on alc883 card (asus p5kc MB)

[dreamer538]

when i'm trying to watch avi with ac3 in quicktime, it freezes for ~10sec. Then video is coming, but it's not synchronized with audio. I'm getting this into console:

10/23/08 9:55:08 PM quicklookd[377] [QL ERROR] 'Creating thumbnail' timed out for '<QLThumbnailRequest /Volumes/public/pub/mult/alesha_popovich_i_tugarin_zmey.avi>'
