If you want to use these two cards together, then syncing with SPDIF is 
pretty much required.  The alsa_in/out programs add latency, and as the 
website said, you should not record using those programs.

I can guarantee that you'd need to sync them with SPDIF under Windows as
well as Linux, or you'll get clock drift between the cards.

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.
