Hey all, Thanks for all the help in my previous post (quad g5 not powering up). Apple has dispatched someone to the studio and they'll be here tomorrow. But...alas...another issue. I have had this happen on my dual g5 at home too...but the audio seems to magically shift to the left channel. Probably about 65/35 in favor of the left. Has anyone heard of this? What could be causing it? I mean, it's not the end of the world...but it's kind of annoying having to shift it back to center again and again.
