Quattro pcm devices

[Patrick Shirkey <pshirkey@boosthardware.com>]

I'm seeing a problem with using JACK and this usb soundcard.

JACK works with this card on all pcm devices seperately but AFAICT is 
not able to access 2 pcm devices on this card at the same time.

This card has 3 stereo pcm devices.

hw:2,0 - capable of upto 16/44100

hw:2,1
hw:2,2 - capable of upto 24_3LE/96000

No matter what I try with .asoundrc I cannot get JACK to see 2 stereo 
i/o at one time. It hangs on startup.

I think it is because the devices 2,0 and 2,1 point to the same physical 
i/o channels and Jack is being blocked by ALSA from accessing them at 
the same time.

Is there anyway to change the order of the pcm devices so that

2,0 -> 2,2
2,1 -> 2,0
2,2 -> 2,1

If not is there anyway I can specify in the following that 
bindings.0.slave.a is hw:2,1 instead of hw:2,0?

----
pcm.quattro {
         type multi;

         slaves.a.pcm "hw:2,0";
         slaves.a.channels 3;


         bindings.0.slave a;
         bindings.0.channel 0;
         bindings.1.slave a;
         bindings.1.channel 1;
         bindings.2.slave a;
         bindings.2.channel 2;
	
}

ctl.quattro {
         type hw;
         card 0;
}
