Topic: Can Linux and jack be configured to see 2 hdsp cards as one?

Hi All
Is there a way of creating a virtual device to use two rme 1952 cards giving me 32 outputs to use with 2 ddx desks?
thank you

Either with a custom asoundrc file like stated in this thread (http://www.rme-audio.de/forum/viewtopic.php?id=9518) or with jackd audioadapter. In my personal case audioadapter gives me less x-runs.
Start Jack with your first soundcard (hw:0) and then bring up the second with this command in a terminal.
< jack_load -i "-d hw:1 -i26 -o26"  HDSP audioadapter >
you should now see a 2nd Card in Jack-Connections with 26 ins and outs.
You have to adapt this in case you have more than the two cards.

Hope this helps

This is really a great solution than editing the asoundrc. Thanks for the suggestion!
