I can understand if Paul is busy (who isn't?) but I'm either too worn out or not smart enough to figure out alsa all by myself. Now I have this: pcm.merge { type multi; slaves.a.pcm "hw:Pro,0"; slaves.a.channels 2; slaves.b.pcm "hw:Pro,1"; slaves.b.channels 2; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave b; bindings.2.channel 0; bindings.3.slave b; bindings.3.channel 1; } ctl.merge { type hw card 1 } And I get: Tue Jul 10 17:34:50 2012: JACK server starting in realtime mode with priority 70 Tue Jul 10 17:34:50 2012: ERROR: control open "merge" (No such file or directory) Tue Jul 10 17:34:50 2012: ERROR: control open "merge" (No such file or directory) Tue Jul 10 17:34:50 2012: ERROR: Failed to acquire device name : Audio-1 error : Cannot allocate memory Tue Jul 10 17:34:50 2012: ERROR: Audio device merge cannot be acquired...
