This is all acheivable through the ubiquitous .asoundrc file. I think The Alsa
site speaks to the hdsp specifically under .asoundrc.
This assumes that your cards are already set up correctly...one would be card0
slot0 and the other card1 slot1 as you outlined.
The other factor is that the cards can link the internal clocks together such
that one becomes a slave in order to keep the cards in sync.
