Okay, here's where I'm at: Jack compiled okay. 'qjackctl' compiled okay. Now I'm getting this trace from 'qjackctl' for 'jackd' ------------------------ 02:55:54.371 JACK is starting... 02:55:54.372 /usr/local/bin/jackd -R -dalsa -dhw:0 -r96000 -p1024 -n2 -i8 -o8 -zs 02:55:54.383 JACK was started with PID=3706 (0xe7a). jackd 0.98.1 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 = 96000 creating alsa driver ... hw:0|hw:0|1024|2|96000|8|8|nomon|swmeter|-|32bit jackd: pcm.c:690: snd_pcm_nonblock: Assertion `pcm' failed. 02:55:54.414 JACK was stopped successfully. 02:55:57.556 Could not connect to JACK server as client. ------------------------ Also, other utilities (alsamixer and envy24control) don't seem to see 'hw:0' either. Seems like I'm ready for clue #2. Ideas anyone? Yhanks in advance, ~Jos~
