It has one pcm device yes. hw1:0

I think I found the reason though I have changed my .asoundrc slightly.
----
pcm.multi {
         type multi;

         slaves.a.pcm "hw:0,0";
         slaves.a.channels 1;
         slaves.b.pcm "hw:0,1";
         slaves.b.channels 1;
	
         slaves.c.pcm "hw:1,0";
         slaves.c.channels 1;
	
         bindings.0.slave a;
         bindings.0.channel 0;
         bindings.1.slave b;
         bindings.1.channel 0;

         bindings.2.slave c;
         bindings.2.channel 0;
}

# jack will be unhappy if there is no mixer to talk to, so we set
# this to card 0.
ctl.multi {
         type hw;
         card 0;
}


----
# arecord -f cd -D multi -c 3 | aplay -D multi
ALSA lib pcm_hw.c:797:(snd_pcm_hw_open) open /dev/snd/pcmC0D1c failed: 
No such file or directory
arecord: main:447: audio open error: No such file or directory
aplay: playback:1739: read error

Is there anyway to fake a capture channel so that I can get the cmipci 
to work with this?

I imagine that it is something to do with

         bindings.1.slave b;
         bindings.1.channel 0;
