Hi All,
I'm trying to use 2 RME Raydat cards simultaneously with jack. I added this .asoundrc [1] and jack
reports this:
~$ jackd -d alsa -d DualRays
jackdmp 1.9.11
...
I have read, that JACK versions 0.x are preferrable for ALSA multi devices.
Did you sync your cards? It's possible via wordclock or S/PDIF. The second card must be set to take
it's clock from the respective input.
...
~$ cat .asoundrc
ctl.DualRays {
type hw;
card 0;
}
pcm.DualRays {
type multi;
slaves.a.pcm "hw:0,0";
slaves.a.channels 32;
slaves.b.pcm "hw:1,0";
slaves.b.channels 32;
I have used two devices, one for input and output respectively. This article may help, even though
it is written for the M-Audio Delta cards. Be sure to use the correct channel count. Some cards -
due to their chips - have more channels than you can really use.

Good luck!

Thanks for the pointers. I could understand that you need to define ctl and pcm for both capture and
playback and use the number of channels of the card (36) and not the number of channels really used (32)
