Hi Thomas, > I bought two Delta 1010LT soundcards.

I can't help you out of firsthand experience (I just have one Delta1010), but I believe this page addresses your question (using a RME Hammerfall example) http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php Also note that you probably need to sync your Deltas externally using Wordclock.
