Fair enough. Ubuntu Studio next time?

In the meantime, maybe someone else could help me? I can understand if Paul is busy (who isn't?) but I'm either too worn out or not smart enough to figure out alsa all by myself.

Now I have this:

pcm.merge {
type multi;
slaves.a.pcm "hw:Pro,0";
slaves.a.channels 2;
slaves.b.pcm "hw:Pro,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.merge {
type hw
card 1
}

And I get:
