This fork is a hard-coded workaround for the issue of being unable to switch between headphones (front case audio out) and speakers (rear case audio out) while both devices were plugged in. It simply displays an option in GNOME's volume menu, and calls a wrapper script for amixer to set the volume levels accordingly.
The extension expects the switchAudioSources script that is contained in the repository root to be copied/moved to ~/Scripts/. If you wish to store the script somewhere else, make sure to modify the filepath constant at the top of the extension.js file.
The script uses alsa sound card #1, and assumes the simple mixer control names 'Headphone' and 'Front' for the headphone and speaker outs, respectively. To tweak this configuration for your setup, modify the switchAudioSources script at the root of this repository. If you don't know which card or simple mixer controls to use, run alsamixer and cycle through the sound cards (F6) and the simple mixer controls for each until you are able to manually adjust the volume for both your headphones and your speakers.
Once the script is configured for your setup, you should be able to switch between devices by running switchAudioSources front or switchAudioSources back. Once this is working, the extension should be ready to use.
This extension was developed using GNOME 3.30.2. The extension should work for versions going back to 3.10, but testing still needs to be performed.
This extension adds a little entry to the status-menu that lets you choose between headphones and speaker outputs.
This extension is based on kgaut's work at https://github.com/kgaut/gnome-shell-audio-output-swticher which was in turn based on anduchs' work at https://github.com/anduchs/audio-output-switcher but it's not supporting last versions of gnome-shell.
Either via
via git
git clone git@github.com:CReviere/gnome-shell-audio-output-switcher-workaround.git ~/.local/share/gnome-shell/extensions/gnome-shell-simple-mixer-contorol-selector-workaround@CReviere
Then restart the gnome-shell via ALT+F2 r and enable the extension using gnome-tweak-tool
To update later, just issue
(cd ~/.local/share/gnome-shell/extensions/gnome-shell-audio-output-switcher-workaround@CReviere && git pull)
