I'm not an expert on sound, but it looks like the way
ALSA is installed, your Vortex2 is now your primary
sound card, mapped to /dev/dsp0. There also doesn't
appear to be an entry for your onboard sound (the
C-Media), therefore, you'll probably need to clone the
stuff that ALSA put in, and modify it a bit, something
like this:
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-cmpci
alias sound-slot-0 snd-cmpci
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss
alias snd-card-1 snd-au8830
alias sound-slot-1 snd-au8830
(Note: This may not be exact, as I'm not an ALSA guru,
and I happen to have a Soundblaster Live! 5.1, which
is emu10k1. I think that the C-Media is cmpci, but
I'm not sure. If this works as I typed it in, the
intent is to make the C-Media dsp0 and the Vortex2
dsp1).
Then, check to see that you have a /dev/dsp1, if not,
you'll have to create one with mknod (or maybe the
MAKEDEV script in /dev).
