Aureon71, two parallel stereo outputs

[Andrew Gaydenko <a@gaydenko.com>]

Hi,

I have ice1724 card (Terratec Aureon 7.1 Space, driver is 1.0.8). It has four
analogue stereo outputs. I'd like to use two of these outputs this way:

- line output 1 - stereo channel for head phones (it is the only output with
                  head phones amplifier),

- line output 2 - stereo channel to connect to an external audio amplifier.

How to make .asoundrc file to accomplish this tasks? I understand, some
alsa device must be configured, but it's all I understand :-)

My own attempts results:

I'm able to hear line outputs 1/2/3/4 with appropriate JACK-routing. So, hardware
works. Moreover, I was able to write appropriate qamix XML config file, and all
the controls are in sync with alsamixer. Now I know a mapping between hw:0,0 
subdevices, mixer controls and the card output jacks. But attempts to understand
.asoundrc secrets are not such lucky. For example, 'aplay -D rear/front' gives
the 'Sample format non available' error (without any redefinitions for rear/front
devices).

P.S. I'm ready to test something concerning Aureon71 with alsa from CVS :-)

Thanks!
Andrew
