Hi everyone, I'm having lots of trouble running jack (from jackQtl) in ubuntu studio 8.04 . I am using a USB sound card : Alesis io2 and Jack Xruns like crazy on all settings! I get some error messages at start up :
11:01:39.739 Startup script terminated with exit status=256. 11:01:39.740 JACK is starting... 11:01:39.740 /usr/bin/jackd -R -P70 -dalsa -dhw:1 -r48000 -p128 -n3 -D -Chw:1 -i2 -o2 11:01:39.744 JACK was started with PID=7429. 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. cannot lock down memory for jackd (Cannot allocate memory) loading driver .. apparent rate = 48000 creating alsa driver ... hw:1|hw:1|128|3|48000|2|2|nomon|swmeter|-|32bit control device hw:1 configuring for 48000Hz, period = 128 frames (2.7 ms), buffer = 3 periods ALSA: final selected sample format for capture: 24bit little-endian ALSA: use 3 periods for capture ALSA: final selected sample format for playback: 24bit little-endian ALSA: use 3 periods for playback JACK: unable to mlock() port buffers: Cannot allocate memory JACK: unable to mlock() port buffers: Cannot allocate memory 11:01:41.796 Server configuration saved to "/home/rob/.jackdrc". 11:01:41.797 Statistics reset. 11:01:41.799 Client activated. 11:01:41.800 JACK connection change. 11:01:41.804 JACK connection graph change. cannot lock down memory for RT thread (Cannot allocate memory) 11:01:56.259 XRUN callback (1).
