Does any of this sound familiar to anyone? Hi Michael, I've got your same problem and asked here few months ago. I'm also running alsa 1.0.11 (with the new one...new problems!). - arecord -f cd -D hw:1 -c 2 file01.wav OK - arecord -f cd -D hw:1 -c 4 file01.wav arecord: set_params:906 Channels count not available (same with hw:1,0 and hw:1,1) - arecord -f cd -D hw:1,2 -c 4 file01.wav arecord: main:547: audio open error: device busy Running jackd, it can't open 'hw:1,1' and 'hw:1,2' is already in use. If I add '-i 4' I get: ALSA: cannot set channel capture count to 4 for capture ALSA: cannot configure capture channel cannot load driver module alsa. No way to start Qjackctrl, for me. In Summer there was a bug (regarding tascam) fixed by jackd developers, so be sure to use the release that works with us428. Sorry to be unhelpful. Good luck. gtrfree ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
