[LAU] I really need help with jack

I've decided that the only way I'm going to get my system to record anything decent is to use jackd. But, I'm being a total idiot with this ... First off, I have the the following devices: bob$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC883 Analog [ALC883 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: SB [HDA ATI SB], device 1: ALC883 Digital [ALC883 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: CODEC [USB Audio CODEC], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 The 2nd one is a spdif speaker attached to the mother board. For now, lets try to get jack working with this. pasuspender -- jackd -d alsa "ALC883 Digital" (BTW, I tried hw0,1 and some other combinations ... but they are the same results) After the command I get: bob$ pasuspender -- jackd -d alsa "ALC883 Digital" jackd 0.121.2 Copyright 2001-2009 Paul Davis, Stephane Letz, Jack O'Quinn, Torben Hohn 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. cannot lock down memory for jackd (Cannot allocate memory) loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods ALSA: final selected sample format for capture: 32bit integer little-endian ALSA: use 2 periods for capture ALSA: final selected sample format for playback: 32bit integer little-endian ALSA: use 2 periods for playback JACK: unable to mlock() port buffers: Cannot allocate memory JACK: unable to mlock() port buffers: Cannot allocate memory **** alsa_pcm: xrun of at least 0.033 msecs Which seems to be okay? Now, I run audacity. Got jack as an output option and load a file. Play it ... the VU meter shows, but no audio. NADA. Just silence. If I can't get a simple play to work, I fear becoming a recording star is out of my reach! Please, this shouldn't be that hard??? -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca
