Or if you are using alsa, trying setting up some aliases.  I have this 
in my modules.conf and it seems to work for me:

      alias snd-card-0 snd-intel8x0
      alias sound-slot-0 snd-intel8x0

      alias snd-card-1 snd-bt87x
      alias sound-slot-1 snd-bt87x

      alias snd-card-2 cx88_alsa
      alias sound-slot-2 cx88_alsa
