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 In this example, a Creative Labs Audigy is set to card 0 for normal file playback, an RME Hammerfall is card 1 for jackd, and a USB midi connector is card 2.
