what about a playing CD? the analog audio outs on the cd are hooked up to the analog bits of the ac97. maestro.c currently has no way of knowing if that stuff is making noise or not. now, if you add _output_ mixers being zeroed to the requirement then you can safely power down everyone involved.

If this could be made reliable I'd be all for it :) I'd worry about sketchy drives. I know the drive in my laptop does very wacky things on coming back from resume. [given the behaviour of varios cd players, it sesms that requests to play still work, but track queries don't. not that I've really investigated]
