I've been poking around with the sound to see if I could find something. It seems that if I run alsaconf in account one it'll work in account one but not in account two or root. If I run alsaconf in account two it works in account two but stops working in account one and won't run in root. If I run alsaconf in root it only works in root and not in either of the other accounts. I also noticed that in PCC/System/Manager is shows that alsa is running. If I click on a sound file and tell it to open in MPlayer the MPlayer control panel shows it running but no sound. I don't know if any of this is helpful, just thought I'd pass it on.
