Another update. It seem all I need to do to get sound back is run alsaconf (take all the defaults) and reboot. I'm not sure why it stops working after two or three reboots, but if I run alsaconf again and reboot it's back. It never works right after alsaconf, it always needs a reboot. It would be nice if the sound state didn't get lost, but at least I can get it back. I'd also wouldn't mind knowing why it happens. Thanks, dhk
