Hi,
(@admin: no need to review my mail anymore - I wrote it 2 days earlier
with the same content, before subscribing to the list :-)
As I am trying to use 18 channels for wavefield synthesis, I bought 3
cheap 5.1 soundcards with the C-Media CM8738 chip.
I need to configure ALSA to let me use the channels with swonder
(http://swonder.sourceforge.net).
Following the hints on the alsa-website
(http://alsa.opensrc.org/.asoundrc), I wrote the following .asoundrc:
------------------------------------
ctl.multi {
type hw
card 0
}
pcm.multi {
type multi;
slaves.a.pcm hw:0;
slaves.a.channels 6;
slaves.b.pcm hw:1;
slaves.b.channels 6;
slaves.c.pcm hw:2;
slaves.c.channels 6;
bindings.0.slave a;
bindings.0.channel 0;
bindings.1.slave a;
bindings.1.channel 1;
bindings.2.slave a;
bindings.2.channel 2;
bindings.3.slave a;
bindings.3.channel 3;
bindings.4.slave a;
bindings.4.channel 4;
bindings.5.slave a;
bindings.5.channel 5;
bindings.6.slave b;
bindings.6.channel 6;
bindings.7.slave b;
bindings.7.channel 7;
bindings.8.slave b;
bindings.8.channel 8;
bindings.9.slave b;
bindings.9.channel 9;
bindings.10.slave b;
bindings.10.channel 10;
bindings.11.slave b;
bindings.11.channel 11;
bindings.12.slave c;
bindings.12.channel 12;
bindings.13.slave c;
bindings.13.channel 13;
bindings.14.slave c;
bindings.14.channel 14;
bindings.15.slave c;
bindings.15.channel 15;
bindings.16.slave c;
bindings.16.channel 16;
bindings.17.slave c;
bindings.17.channel 17;
}
----------------------------------------
Unfortunately, this config-file doesn't work at all, the device "hw:1"
doesn't seem to exist.
Can anyone help me with the use of multiple soundcards for playback?
Is there anything I have to change in the 'modules.conf' for proper
usage of 3 cards?
Many thanks,
Rolf
