New page

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.
<code>
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
}
</code>

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.

 ) Lastly, check that all of the outputs are turned up in AlsaMixer.  To get to this, open a Terminal in CentOS and type alsamixer at the command prompt.  This will open the Alsa Mixer panel.  Press F6 and select the correct soundcard.  You can now set the output levels.  You are looking for Front (1st O/P), Surround (2nd O/P) , Center and LFE (3rd O/P).  These control the output levels of the different output sockets on the card.  The Master level also controls the master level of all of the outputs.  Once set you can escape from this.

 There you go, you should have multi channel output working on your soundcard.
