From the 64studio FAQ:

I have multiple audio interfaces. How can I make sure they are given 
consistent device numbers by ALSA?

As root, add lines like these to the end of your /etc/modprobe.d/alsa-base 
file:
alias snd-card-0 snd-emu10k1

options snd-emu10k1 index=0

alias snd-card-1 snd-rme9652

options snd-rme9652 index=1

alias snd-card-2 snd-usb-audio

options snd-usb-audio index=2
