[LAU] Problem using 2 RME Raydat

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 Copyright 2001-2005 Paul Davis and others. Copyright 2004-2014 Grame. jackdmp comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK server starting in realtime mode with priority 10 self-connect-mode is "Don't restrict self connect requests" creating alsa driver ...

What should I check? Jackd is working fine with each card independently. Thanks -- Raphaël [1] ~$ 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; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave a; bindings.2.channel 2; bindings.3.slave a; bindings.3.channel 3; bindings.4.slave a; bindings.4.channel 4; bindings.5.slave a; bindings.5.channel 5; bindings.6.slave a; bindings.6.channel 6; bindings.7.slave a; bindings.7.channel 7; bindings.8.slave a; bindings.8.channel 8; bindings.9.slave a; bindings.9.channel 9; bindings.10.slave a; bindings.10.channel 10; bindings.11.slave a; bindings.11.channel 11; bindings.12.slave a; bindings.12.channel 12; bindings.13.slave a; bindings.13.channel 13; bindings.14.slave a; bindings.14.channel 14; bindings.15.slave a; bindings.15.channel 15; bindings.16.slave a; bindings.16.channel 16; bindings.17.slave a; bindings.17.channel 17; bindings.18.slave a; bindings.18.channel 18; bindings.19.slave a; bindings.19.channel 19; bindings.20.slave a; bindings.20.channel 20; bindings.21.slave a; bindings.21.channel 21; bindings.22.slave a; bindings.22.channel 22; bindings.23.slave a; bindings.23.channel 23; bindings.24.slave a; bindings.24.channel 24; bindings.25.slave a; bindings.25.channel 25; bindings.26.slave a; bindings.26.channel 26; bindings.27.slave a; bindings.27.channel 27; bindings.28.slave a; bindings.28.channel 28; bindings.29.slave a; bindings.29.channel 29; bindings.30.slave a; bindings.30.channel 30; bindings.31.slave a; bindings.31.channel 31; bindings.32.slave b; bindings.32.channel 0; bindings.33.slave b; bindings.33.channel 1; bindings.34.slave b; bindings.34.channel 2; bindings.35.slave b; bindings.35.channel 3; bindings.36.slave b; bindings.36.channel 4; bindings.37.slave b; bindings.37.channel 5; bindings.38.slave b; bindings.38.channel 6; bindings.39.slave b; bindings.39.channel 7; bindings.40.slave b; bindings.40.channel 8; bindings.41.slave b; bindings.41.channel 9; bindings.42.slave b; bindings.42.channel 10; bindings.43.slave b; bindings.43.channel 11; bindings.44.slave b; bindings.44.channel 12; bindings.45.slave b; bindings.45.channel 13; bindings.46.slave b; bindings.46.channel 14; bindings.47.slave b; bindings.47.channel 15; bindings.48.slave b; bindings.48.channel 16; bindings.49.slave b; bindings.49.channel 17; bindings.50.slave b; bindings.50.channel 18; bindings.51.slave b; bindings.51.channel 19; bindings.52.slave b; bindings.52.channel 20; bindings.53.slave b; bindings.53.channel 21; bindings.54.slave b; bindings.54.channel 22; bindings.55.slave b; bindings.55.channel 23; bindings.56.slave b; bindings.56.channel 24; bindings.57.slave b; bindings.57.channel 25; bindings.58.slave b; bindings.58.channel 26; bindings.59.slave b; bindings.59.channel 27; bindings.60.slave b; bindings.60.channel 28; bindings.61.slave b; bindings.61.channel 29; bindings.62.slave b; bindings.62.channel 30; bindings.63.slave b; bindings.63.channel 31; }
