Check the ALSA docs, I can't remember the exact details, but there's an option
you can pass to the sound driver module to force a particular order. I think
it's something like:

        options snd-emu10k1 index=0
        options snd-intel8x0 index=1

Something like that. I used to have that problem too and remember fixing it
(but I don't have access to that machine at the moment to check for you).

Cheers,
