I'm not really sure how to do all this but it does seem like a good 
debugging method. Could you be a little bit more explicit about how 
the above steps are carried out?

Tired this, ran "update-modules" and restarted alsa.

This changes the way that the two cards are listed in the /proc/asound/cards
