And how ? If you load the modules with a "index=N" parameter, this will fix the card at number N. Nornally, you do this by sticking options snd-foo index=0 options snd-bar index=1 lines in /etc/modprobe.conf (or /etc/modprobe.d/whatever). Moreover though, you can also address the cards by their name instead of their number. Look in /proc/asound after loading the modules for what the cards call themselves (the value of the symbolic links to the cardN directories) then you can use things like: aplay -D default:NAME foo.wav instead of aplay -D default:0 foo.wav Or, you can force the names: options snd-foo index=0 id=INTERNAL options snd-bar index=1 id=UA-1EX options snd-baz index=2 id=MIDI "aplay -D default:UA-1EX" and similar...
