Now both my ~/.asoundrc and /etc/asound.conf look like follows: ----------------- pcm.multi { type plug slave.pcm { type multi slaves.a { pcm "hw:0" channels 2 } slaves.b { pcm "hw:1" channels 2 } slaves.c { pcm "hw:2" channels 2 } bindings [ { slave a channel 0 } { slave a channel 1 } { slave b channel 0 } { slave b channel 1 } { slave c channel 0 } { slave c channel 1 } ] } } --------------- > and tell Jack to use device name "multi". This is what I get in the messages window of qjackctl: /usr/bin/jackstart -R -dalsa -dmulti -r47040 -p64 -n5 -S -i2 -o2 JACK was started with PID=4250 (0x109a). back from read, ret = 1 errno == Success jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd 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 loading driver .. apparent rate = 47040 creating alsa driver ... multi|multi|64|5|47040|2|2|nomon|swmeter|-|16bit ALSA lib pcm.c:1972:(snd_pcm_open_noupdate) Unknown PCM multi ALSA lib pcm.c:1972:(snd_pcm_open_noupdate) Unknown PCM multi ALSA: Cannot open PCM device alsa_pcm for playback.
