ALSA/Audigy Multichannel Setup Old
From Rivendell Wiki
I have an Audigy 1 card that I wanted to be able to use the surround outs as a separate output on my board. After messing with my .asoundrc file, here's the config that worked.
pcm.rd0 {
type plug
slave {
pcm "front"
}
}
ctl.rd0 {
type hw
card 0
}
pcm.rd1 {
type plug
slave {
pcm "rear"
}
}
ctl.rd1 {
type hw
card 0
}
I believe the "rear" and "front" keywords are unique to the Audigy emu10k1 driver, not every Alsa card driver will include them.
I also came very close using the Alsa dmix plugin, but the output from Rivendell was unusable.
