Hi,
I'm posting to this list hoping to get some directions. I'm trying to
setup a Linux system (Ubuntu/Debian) with PD and a SB Live 5.1 PCI card
using 4 channel output. Is this even possible?
I'm hoping to use 4 audio channels with PD and the SB Live. I've been
looking how to accomplish this. I'm now looking into the .asoundrc
config files. I've tried different setups but I haven't been able to get
PD to use 4 channels of the card, only 2 channels. This is what I have
done so far:

Ok, doing some extensive reading I've gotten it to work the way I wanted
it. Though it was extremely hard to find the correct documents at the
end it was very easy to setup. So this is for the archives:
I'm using a SB Live PCI card on a Linux system:
cat /proc/asound/cards
0 [Live ]: EMU10K1 - SBLive! Value [CT4780]
SBLive! Value [CT4780] (rev.7, serial:0x80221102)
at 0xece0, irq 177
Out of the box I couldn't get it to use four channel output so I made a
.asoundrc file:
pcm.SBlive4ch {
type route;
slave.pcm surround40;
slave.channels 4;
ttable.0.0 1;
ttable.1.1 1;
ttable.2.2 1;
ttable.3.3 1;
}
Then I start pd:
pd -alsa -alsaadd SBlive4ch -audiooutdev 3 -noadc -outchannels 4
I then get a correct working setup.
I also noticed I could just use "-alsaadd surround40" but I got some
errors about the DAC being locked. I haven't had that yet with my own
defined .asoundrc.
Rg,
Arnaud.
