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