hi,
I don't see the part were you bind the two devices together. I think this
is achieved in my .asoundrc by this section:
pcm.quattro {
type multi;
slaves.a.pcm "hw:Quattro,0";
slaves.a.channels 2;
slaves.b.pcm "hw:Quattro,1";
slaves.b.channels 2;
bindings.0.slave a;
bindings.0.channel 0;
bindings.1.slave a;
bindings.1.channel 1;
bindings.2.slave b;
bindings.2.channel 0;
bindings.3.slave b;
bindings.3.channel 1;
}
ctl.quattro {
type hw;
card Quattro;
}
Using this definition I'm able to get snd to use this device with
MUS_ALSA_DEVICE=quattro
but I couldn't get other applications to use the 4 channels.
Another potential source of problem was (is?) which soundcard is first
first in the system order (usb & builtin). At least in FC8 I found that
this whole arrangement only worked if the USB card was the first one. I
think this is no longer a problem but I'm not sure.
hope that helps
Pded
