jack-select 0.4b1

A systray app to set the JACK configuration from QjackCtl presets via DBus

A systray application to quickly change the JACK configuration from QjackCtl presets via DBus.

Overview

This application displays an icon in the system tray (also known as notification area) of your desktop, which shows the status of the JACK audio server and when you click on it, a menu pops up which lets you quickly select from the JACK configuration presets you created with QjackCtl. When you select a preset, its JACK engine and driver configuration settings are loaded via DBus into JACK and then the server is restarted. This allows you to switch between different audio setups with just two mouse clicks.

Screenshot of the pop menu

When you hover with the mouse pointer over the systray icon and JACK is running, a tooltip will show you the name of the active preset (if known), the most important parameters of the current setup and some server statistics.

Lastly, there are menu entries to stop the JACK server and to quit the application.

To create or edit presets, just use the QjackCtl configuration dialog and make sure you close it with “Ok” so the changes are saved. jack-select will pick up the changes automatically.

Installation

To install jack-select on your system for everybody, check and install the requirements below and then run:

$ git clone https://github.com/SpotlightKid/jack-select
$ cd jack-select
$ [sudo] make PREFIX=/usr install

This will install the jack-select program, the jackselect Python package and the jack-select.desktop file and the jack-select.png icon to provide a desktop start menu entry. It will also install the required Python dependencies if they haven’t been installed yet. Installing PyGObject probably won’t work this way, so make sure it is installed some other way beforehand, e.g. via your distributions package management.

If you want to install jack-select only for the current user, replace the last command above with:

$ make install-user

You can start jack-select from your desktop’s XDG-compatible start menu or add it to your autostart folder (e.g. ~/.config/autostart) to have it started along your with your desktop.

Requirements

This application works with the DBus-version of JACK only.

It written in Python 3 using the PyGobject bindings for GTK 3. In addition to this, the following third-party Python libraries are required:

• pyxdg

• dbus-python

These may be available from the package repository of your distribution as python-gobject, python-xdg and python-dbus respectively.

Python 2 is not supported.
