How to run two soundcards?

Here's a pretty simple setup how to bring two soundcards to work..

Build both drivers as module into your kernel and add the following to your /etc/modprobe.d/alsa.conf:

alias snd-card-0 <driver1>
alias sound-slot-0 <driver1>
alias snd-card-1 <driver2>
alias sound-slot-1 <driver2>


Replace <driver1> and <driver2> with your own soundcard modules.

I'm using pulseaudio to manage the different sinks.
