You're likely using jackdbus in combination with pulseaudio. Regarding a short web research the above jackd line, jackd -dalsa -dhw:0 -r48000 -p256 -n2 for jackdbus, would be a script: #!/bin/dash jack_control start jack_control eps realtime true jack_control ds alsa jack_control dps device hw:0 jack_control dps rate 48000 jack_control dps nperiods 2 jack_control dps period 256 exit It becomes a complex script, if you want to read the last settings used with QjackCtl and stored as $HOME/.jackdrc and then add those values to the jack_control command. Perhaps QjackCtl could generate a similar file with jack_control commands, or you simply edit the script, if you want to change the settings. I don't know how pulseaudio and the sink thingy interact. They seemingly correspondent by dbus. Open an editor and copy and paste the text from #!/bin/dash to exit to the editor, save it, e.g. name it auto-jack.sh , after that make it executable with chmod: [rocketmouse@archlinux tmp]$ ls -l auto-jack.sh -rw-r--r-- 1 rocketmouse rocketmouse 201 Jul 9 22:42 auto-jack.sh [rocketmouse@archlinux tmp]$ chmod a+x auto-jack.sh [rocketmouse@archlinux tmp]$ ls -l auto-jack.sh -rwxr-xr-x 1 rocketmouse rocketmouse 201 Jul 9 22:42 auto-jack.sh Start it by running /path/auto-jack.sh but don't chose /tmp as the directory, I'm using the temporary directory only, because I never ever will use jackdbus myself. [rocketmouse@archlinux tmp]$ /tmp/auto-jack.sh --- start --- engine param set "realtime" -> "true" --- driver select "alsa" --- driver param set "device" -> "hw:0" --- driver param set "rate" -> "48000" --- driver param set "nperiods" -> "2" --- driver param set "period" -> "256" 1. I don't have pulseaudio installed, so I can't test, if it automatically comes with pulseaudio via dbus. 2. The first time I tested the scrip, not all IOs of my audio card were available. Then I killed jackdbus, launched jackd, terminated jackd and launched jackdbus by the script again, after that all IOs were available. IOW I can't help, because I'm a plain ALSA and jackd user. The pulseaudio crowed needs to chime in.
