Thanks. Clearly there is no ALSA driver loaded. But your soundcard worked 
before your "Grub boot confusion" problem, right?

I really don't know what's the matter, but you could always try "sudo 
modprobe snd-atiixp" to try to load the driver manually, and then see if 
the commands you used before now give different results.

Good luck!
