I have a set of USB Headphones and a set of speakers which I switch between depending on what I'm listening to. In ever other desktop environment i've tried I usually have an icon which will give me some basic options like volume and switching the output.
I have a volume icon with a volume slider and controls for the music player and sound settings which takes me to the PulseAudio volume control which as far as I can tell doesn't have an option to change which source to output sound? I can change it for an individual application when the application is running but not overall.
How can I change the sound output?
Try installing pavucontrol (PulseAudio Volume Control) from the software centre. It should give you more options.
I already have Pulse Audio control but as far as I can tell you cant switch output device for all just by application when the application is running. Or have I missed something?
I don't have a similar setup to test, but do you not have the option to select which output device on the "Output" tab?
