You must have a file called /etc/modules.d/alsa
You must be sure to define the card_index and for each sound card, and the
cards_limits option. As example:
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-1 snd-usb-audio
options snd-usb-audio index=1
options snd cards_limit=2
After, run 'update-modules' and '/etc/init.d/alsasound restart'
With those options, udev will know in which order to load the sound card. It is
a file alsa-configuration.txt with the kernel sources or the alsa driver
package that explain more.
