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,
