[edit] Multiple soundcards in Gentoo

In this setup the cards get a specific order nothing more, the first one (audigy) is the default card which amarok, mplayer,... will use
You could of course also compile the kernel without the second driver.


sample /etc/modules.d/alsa file for multiple soundcards
1. snd-ca0106 (creative audigy ls)
2. snd-intel8x0 (onboard)


options snd-ca0106 index=0
options snd-intel8x0 index=1
#
alias snd-card-0 snd-ca0106
alias snd-slot-0 snd-card-0
alias sound-slot-0 snd-slot-0
#
alias snd-card-1 snd-intel8x0
alias snd-slot-1 snd-card-1
alias sound-slot-1 snd-slot-1


after that you need to run: 

modules-update && /etc/init.d/alsasound restart



Howto get the needed information:

(current sound card order can change because udev loads the modules in random order. dont know about drivers compiled in the kernel)

cat /proc/asound/cards 

0 [CA0106         ]: CA0106 - CA0106
                     Audigy SE [SB0570] at 0xdf00 irq 19
1 [CK804          ]: NFORCE - NVidia CK804
                     NVidia CK804 with ALC655 at 0xfebfd000, irq 22


(used modules)
cat /proc/asound/modules 

0 snd_ca0106
1 snd_intel8x0
