Hi! I'm trying to merge two ICE1712 based soundcards, so they appear as one big soundcard in JACK. I tried it as described on John Lapeyre's website: http://www.johnlapeyre.com/linux_audio/linux_audio.html That is, I recompiled libasound2 1.0.14-rc3 with the following patch: http://www.johnlapeyre.com/linux_audio/pcm_multi.patch And compiled JACK 0.109 accordingly and finally installed the .asoundrc file, listed here: http://www.sound-man.co.uk/linuxaudio/ice1712multi.html However when I try to start jackd with: usr/bin/jackd -t 4999 -s -R -m -d alsa -C multi_capture -P multi_playback -p 128 -n 2 -r 44100 it fails with the following messages: jackd 0.109.2 Copyright 2001-2005 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 JACK compiled with System V SHM support. loading driver .. apparent rate = 44100 creating alsa driver ... multi_playback|multi_capture|128|2|44100|0|0|nomon| swmeter|-|32bit ALSA lib pcm_hw.c:1357:(_snd_pcm_hw_open) Invalid value for card ALSA lib pcm_hw.c:1357:(_snd_pcm_hw_open) Invalid value for card cannot load driver module alsa no message buffer overruns The target system is a Debian system and I wasn't really sure where to install the .asoundrc file, so installed it as /etc/asound.conf, /etc/alsa/asound.conf and in the home directory as .asoundrc Does anybody have an idea what could be wrong or could give me pointers how to debug it?
