From what I can remember, /dev/snd/hwC0D0 appeared after upgrading to ALSA 1.0.19 . Have you upgraded yet or are you still on 1.0.18 (Jaunty's default?). Run "cat /proc/asound/version" to see your version.
I'm now on 1.0.20 and it is actually working better as I can play multiple sources at the same time. This did not work for me on 1.0.19 .

I advise using the script here documented and located here: http:// ubuntuforums. org/showthread. php?p=6589810 to upgrade your ALSA version if you haven't done it yet.
