Installed Ubuntu 18.10 and I'm very happy.
The only function i'm missing is quick switching audio output profiles of my soundcard.
In tray menu only volume control is possible, therefore I tried GNOME Shell Extension: Audio output selector, but it only switches between soundcards (internal speakers & USB soundcard) from the tray menu.
I need to switch between the USB soundcard outputs (headphones & 3,5mm audio-out). These are shown as Output profiles "Speaker" & "Headphone".
How can I enable a quick way to switch between these profiles? It's strange Ubuntu doesn't support any quick way to switch audio output from tray. :(
thanks Pappl
