I have the same I guess, but on different hardware (also uses the snd_hda_intel driver though)
Using 2.6.22-9-generic it works straight away but with 2.6.22-10-generic mixers are gone and the alsa device name changed a little. Feisty also had this behavior by the way, I used snd_hda_intel supplied by Via to solve that.
