I've put up how I got it to work here:
http://delta.brainiac.com/deltasync.html
I run 2 Delta 1010s synced up and it works well for me.
I tried this setup on Puredyne 911 (based on Ubuntu Karmic, but without
pulseaudio).
I added the suggested lines in /etc/modprobe.d/alsa-base.conf to get the
m-audio cards to load first.
I added the ~/.asoundrc with the suggested content.
At least the ~./asoundrc didn't seem to work.
Perhaps on Ubuntu Karmic this needs to be done differently?
