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!
