What's happening is that all audio playback in iTunes and Quicktime is sounding horribly mushy. I've had this problem before but the fix was simply removing third party plugins. Then the sound quality returned to normal. Nothing has changed with respect to my speakers, receiver, etc. Also, I am current on all software updates. One thing I haven't checked is this... I'm currently synching my iPhone. I haven't verified yet if the sound playback is normal while not synching. I would normally doubt this would be the problem but with many people reporting, including myself, that iPhone is taking a long time to synch to iTunes 7.7, I wonder if there aren't other things going funky during synch. But I don't have any third party plug-ins installed at this time. Any ideas on the problem and the fix?
