Yeah. it happens also on the Tibooks. Rarely, but usually when you dont
expect it, and when everyone else just fell asleep.. :-]
Sometimes removing the sound driver stops the noise. I think the reason
why it happens is that it sets the mic input to full max, and also
monitors it from the speaker, which, on the tibook, is next to the mic..
so it sounds like feedback noise. Since the sound changes if you tap the
mic with your finger when it screams. (tibook's mic is next to the left
speaker)
But yea, removing the sounddriver prior going to sleep might work,
though it probably sucks since it means you need to quit all your sound
related apps so that the sound device is freed :-/
