Does Ubuntu use the alsa provided init db (alsactl init 0 - where 0 is card number IIRC) or it's own system? I seem to recall it had it's own system at some point, but not really sure (either if I'm remembering correctly or if it's still used). Perhaps alsactl init 0 will help?

10.04 LTS and earlier use a crufty distro-maintained version. 10.10
and newer will use the init db (though we still have to figure out how
to differentiate the massively poor '{Audigy,SB Live} Analog/Digital
Output' mess, among others).
alsactl init is most definitely the way to go.
