Hi Thomas,
I bought two Delta 1010LT soundcards. Each card has 8
analog I/O.
With Ardour i want to record (and playback) 16 analog channels at once.
AFAIK Jack only supports one soundcard at a time?
So i tried the "multi"-plugin of ALSA (.asoundrc), but had no luck.
The 1010LT has 12 capture and 10 playback channels and "multi" seems to need
synchronous I/O?
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.
Cheers,
Walco
