Re: [Jack-Devel] (no subject)

I just installed Ubuntu trusty (on crouton on an Acer Chromebook), and am trying to get sound going (so I can run Super-Collider.) Upon the advice of various webpages I've come across that discuss installation of Super-Collider, I've tried: - removing pulseaudio - adding myself to the "hwaudio" group - adding '@audio' entries to /etc/security/limits.conf But I always get "Could not connect to JACK server as client" when I run qjackctl. This is the output I get when I run qjackctl. I've tried changing the interface to both 'cras' and 'hw:DAISY12S', but neither work. 23:54:23.518 Patchbay deactivated. 23:54:23.585 Statistics reset. 23:54:23.598 ALSA connection change. 23:54:23.643 D-BUS: Service not available (org.jackaudio.service aka jackdbus). 23:54:23.667 JACK is starting... 23:54:23.668 /usr/bin/jackd -dalsa -dcras -r44100 -p1024 -n2 23:54:23.686 ALSA connection graph change. jackd 0.122.0 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. loading driver .. apparent rate = 44100 creating alsa driver ... cras|cras|1024|2|44100|0|0|nomon|swmeter|-|32bit Couldn't connect to cras. control open "cras" (Operation not permitted) configuring for 44100Hz, period = 1024 frames (23.2 ms), buffer = 2 periods ALSA: final selected sample format for capture: 32bit integer little-endian ALSA: use 2 periods for capture ALSA: cannot set hardware parameters for capture ALSA: cannot configure capture channel cannot load driver module alsa (qjackctl:13298): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed (qjackctl:13298): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed 23:54:23.980 JACK was started with PID=13310. 23:54:24.042 JACK was stopped successfully. My apologies if I'm asking this in the wrong place, or if I'm not giving enough info. I'll ask elsewhere if that's more appropriate. But any advice or suggestions would be much appreciated! _______________________________________________ Jack-Devel mailing list Jack-Devel(a)lists.jackaudio.org http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org
