This extension adds a little entry to the status-menu that shows the currently selected pulse-audio-output device. Clicking on that will open a submenu with all available output devices and let's you choose which one to use.
Since version 5, it also provides a shortcut to quickly switch output sources:
<Super>+q
Version 16 removes the shortcut until it can be customized.
Most importantly this extension is as simple as possible. Therefore it does not include an input switcher or similar. See Audio-Input-Switcher (https://github.com/anduchs/audio-input-switcher) extension for microphone selection.
Either via
https://extensions.gnome.org
or via
git clone https://github.com/adaxi/audio-output-switcher.git ~/.local/share/gnome-shell/extensions/audio-output-switcher@anduchs
Then resart the gnome-shell via Alt+F2 then r and enable the extension using gnome-tweak-tool
To update later, just issue
(cd ~/.local/share/gnome-shell/extensions/audio-output-switcher@anduchs && git pull)

PIHKAL FORK CHANGES: Trigger reload of PulseAudio-Equalizer after setting the new sink. Probably not useful for many people but does what I need it to do.
