there are no pseudo-outs AFAIK.

you need to understand that Ardour does *not* alter the settings of the
h/w mixer in your audio interface. if you do not get the h/w mixer setup
correctly, ardour won't change it for better or worse.

in your case, it sounds as if you do not have input routing set up
correctly, so that capture is collecting data sent to the outputs by
ardour. i don't use ice1712-based h/w myself, but i know there are other
people here with lots of envy24control experience.
