In this case I'm trying to load 2 cards with a single interface as

described here: http://delta.brainiac.com/deltasync.html
I'm investigating the way the system is setup (Puredyne 911), whether

alsa reads ~/.asoundrc or not.

It seems to me that the way alsa works and is configured has changed a

bit over the years, so perhaps it will take some tweaking to get this

particular setup to work.
As a footnote, getting puredata to use multiple cards using OSS seems to

work pretty well (I suppose this is a builtin feature for puredata).

After a quick test I did not hear any clicks (don't know if my spdif

sync between the m-audio delta cards is set up right, and I have no way

to tell as of now).
