I can now open Qjackctl using the terminal. This is the code that I am using.

pulseaudio --kill
jack_control  start

This will open the program successfully. Then when I am finished I can type this code:

jack_control exit
pulseaudio --start

It takes a little bit of typing, but it works. How do I save the commands and make it work automatically? Thanks in advance for all of your help.

You can create a .desktop file for doing this.

First, create a script using terminal:

mkdir -p bin
gedit ~/bin/jack_control.sh

In the new opened file, add the following lines:

#!/bin/bash

pid=$(pgrep -x jack_control)

if [ "$pid" = "" ]; then 
    pulseaudio --kill
    jack_control  start
else
    jack_control exit
    pulseaudio --start
fi

Save the file, close it and make it executable:

chmod +x ~/bin/jack_control.sh

Now you can create your .desktop file:

gedit ~/Desktop/jack_control.desktop

In the new opened file, add the following lines:

[Desktop Entry]
Version=1.0
Name=Qjackctl
Comment=Start or stop jack_control
Exec=/home/your_username/bin/jack_control.sh
Icon=/path/to/icon.png    # <-- this line is optional
Terminal=false
Type=Application
Categories=Utility;Application;

Save the file, close it and make it executable:

chmod +x ~/Desktop/jack_control.desktop

Finally, go to desktop and test your new .desktop file.

  • Hello, I really appreciate your help. I did what you said but got this error message- Could not find the home/brian/-Desktop/~jack_control.esktop. Please check that you typed the location correctly and try again. On the line Icon-/path/to/icon.png, are there three spaces between that and # <-- or two? Also, the the words this line is optional, is the for me or part of the text? Sep 5 '13 at 14:50
  • @BJsgoodlife Be careful with the paths. home/brian/-Desktop/~jack_control.esktop it's wrong at all. In desktop file use: Exec=/home/brian/bin/jack_control.sh. That line Icon=/path/to/icon.png # <-- this line is optional as says is optional. This is a comment: # <-- this line is optional, so delete it. If you want to assign an icon to your desktop file, then change /path/to/icon.png with the path to the icon; if you don't want, delete that line. Sep 5 '13 at 15:10
  • Ok I got it to work but then it stopped working again. I have done it a number of times, so maybe what I need to do is delete all the files and start over. How do you do that? Sep 6 '13 at 4:29
  • @BJsgoodlife There are only 2 files: ~/bin/jack_control.sh and ~/Desktop/jack_control.desktop; ~ stands for /home/brian (in your case) - these are equivalent. Sep 6 '13 at 4:37

I wrote this to be as fast and simple to use as possible - this script will work great in tandem with a quick access terminal like Yakuake or Guake:

#!/bin/bash

####################################################
#
# Use this CLI util to toggle pulse audio <--> jackd
#
# This program will start by shutting down the
# pulseaudio systems and starting up a jack daemon.
# It'll then wait for you to press any key. When you
# do, it'll close the jack daemon and restart pulse.
#
####################################################

function write() {
  echo -e "\033[036m`basename $0:`#\033[0m $1"
}

pulseaudio --kill
jack_control start

write 'press any key to toggle back to pulseaudio..'
read

jack_control exit
pulseaudio --start

Save this to a file named qjack (or whatever) that's in your $PATH, chmod 755 qjack to make it executable.
