i have the same audio device and it's working now:
add _hxxp://download.opensuse.org/repositories/multimedia:/audio/openSUSE_10.3 to your repositories and update alsa (and related) packages from there; you might also need the alsa-driver-kmp-default-1.0.15.hg20071011_2.6.22.5_31-1.1.x86_64.rpm.
good luck!
