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,
