Saw that coming, eh?
For whatever reason, unless I have the iTunes volume turned all the way up, the sound is *really* garbled and staticy. Full volume, works GREAT, but is a little annoying, because it does interfere a little with other sounds, and I can't nudge it downwards at *all*, or things go south.
I've done their suggested tweaks, and even completely uninstalled iTunes and QuickTime, then reinstalled. I've probably stumbled upon a new problem with the new version...
