Also, it seems like you have both the built-in card and sound card
enumerated. If you would like to use the sound card on that system,
the easiest way to go about it is to first go into BIOS and disabling
built-in audio, though you could also force ALSA to allocate the
SoundBlaster to the default slot if you prefer. In Ubuntu 10.10, you
can do <sudo nano /etc/modprobe.d/alsa-base.conf> in a terminal and
try adding <options snd-hda-intel index=-2> to the bottom, CTRL-O,
then <sudo alsa force-reload> to restart ALSA.

If you haven't checked it already,
https://help.ubuntu.com/community/HdaIntelSoundHowto might also help,
in particular the first section on manually entering module
parameters.

Donald, I assume you're talking to Chris, but:
