iTunes 7.6 No Audio When Playing a Music Video or Movie
There is no audio when playing a music video or a movie that I've purchased. Movie trailers and music videos in the iTunes store have no audio either. Videos from iTunes University that I've downloaded (such as an MIT lecture) play fine w/ audio.
Music audio (such as tracks I've purchased or tracks on the iTunes store) play fine.
QuickTime videos, such as a QT video on my desktop play fine. Windows Media Player works fine too.
So, why don't music videos and movies play (w/audio) on iTunes 7.6??
