Can't change audio output of running apps in pavucontrol
I have an HDMI Tv plugged in, and want to direct firefox to it.
In PAVUControl, I can see:
Skype, which I already output via HDMI Firefox, outputting via the laptop speakers.
The drop downs for both of these items don't have any further items in them.
If I go to the sound part of GNOME settings, I can choose different global outputs and test those.
Output of pw-dump is here https://gist.github.com/stuaxo/ca0d3655d1f70b80266cdce72b09129a
