 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=3D0
alias snd-card-1 snd-usb-audio
options snd-usb-audio index=3D1
options snd cards_limit=3D2

After, run 'update-modules' and '/etc/init.d/alsasound restart'

With those options, udev will know in which order to load the sound card. I=
t is
a file alsa-configuration.txt with the kernel sources or the alsa driver
package that explain more.
