macgallant said:Zapping the pram didn't fix the audio volume problem for me. it's still loud, I either have to unplug and replug my speakers or to put my system to sleep then wake it (this causes the system sound to have it's actual volume displayed) and manually set it back to 10/16 volume. I didn't have to distortion problem though, just the volume problem.
Note to MDD owners: We got to notify Apple about this!
I sent a bug report to Apple through their site > Mac OS X > Feedback. I tried zapping PRAM and going to open firmware [reset-nvram, reset-all] and that didn't help me either. Looks like it'll take a software fix from Apple
