Jack server is not running or cannot be started The log from the most recent attempt (after adding myself to audio group, running qjackctl through pasuspender, driver is alsa, interface is hw:NVidia) is: 20:13:47.156 Statistics reset.Ģ0:13:47.172 D-BUS: Service is available ( aka jackdbus).Ĭannot connect to server socket err = No such file or directory I also added myself to the audio group, following this, which seems to have stopped it from hitting memory errors. I tried pasuspender qjackctl but JACK still wouldn't start. Pulseaudio does exist on my system and is currently running. I tried changing PCH to Nvidia but it didn't help Ardour changed it back and the other devices don't show up in Ardour's config stuff. ~/.jackdrc had /usr/bin/jackd -v -dalsa -dhw:0 -r44100 -p1024 -n2 the first time I looked, but when I opened Ardour it changed to /usr/bin/jackd -t 200 -p 2048 -R -T -d alsa -n 2 -r 44100 -p 1024 -d hw:PCH,0 -X raw. proc/asound/cards has: 0 : HDA-Intel - HDA Intel PCHĪlesis V25 at usb-0000:00:14.0-1, full speed jackd 1.9.11 (installed as dependency of Ardour).Built-in audio on motherboard (not connected to any I/O, but does exist and occasionally confuses applications).One "USB-MIDI keyboard controller" (Alesis V25).If I click Close instead of OK from the Ardour config, I get Could not create session in "/home/qwertystop/multimedia/ardour/testing": Cannot connect to audio/midi engine. I know it isn't (purely) a matter of whether any other applications are playing audio. That hasn't popped up in a while, I don't think I did anything differently between attempts, and unfortunately I did not copy down the exact log message the last time it did come up. In the latter case, scrolling back through them, I found an entry saying that the audio device was already in use, or something similar. When I try to start JACK through Qjackctl (with verbose messages on), it either apparently starts (but does not, as far as I can tell, register any input from my keyboard) or pops up its logs to report a failure. When I try to continue on from there (because I don't expect to be using much memory on it any time soon, since right now I just want to be able to make any sound at all), I get the error error Could not create session in "/home/qwertystop/multimedia/ardour/testing". ![]() You can view the memory limit with 'ulimit -l', and it is normally controlled by /etc/security/nf` This might cause Ardour to run out of memory before your system runs out of memory. When I try to start Ardour, with a new session testing, using JACK as the audio system, I get (on starting JACK) the warning: WARNING: Your system has a limit for maximum amount of locked memory. I would like to set up Ardour and mess around a bit on a keyboard-as-in-music which I got a while ago, turned out not to need, but couldn't return.
