The modules (drivers) used by both cards need to be specified in /etc/modprobe.conf per ALSA documentation. http://www.alsa-project.org/alsa-doc/ Fictional example (don't know if it works) to simultaneously use an M-Audio Delta 1010 and a SoundBlaster Live!: alias snd-card-0 snd-ice1712 options snd-card-0 index=0 alias snd-card-1 snd-emu10k1 options snd-card-1 index=1 When using alsamixer to configure each card, use -c X where X=0,1 to choose the card. > Other suggestions are welcomed too.
