Ubuntu 21.04 - Gnome Sound Panel ignoring output selection

Solution 1:

I solved it by first stopping pulseaudio:

systemctl stop --user pulseaudio.socket
systemctl stop --user pulseaudio.service

Then moving my pulse audio config out of the way

cd ~/.config
mv pulse pulse_old

Then restarted pulseaudio

systemctl start --user pulseaudio.socket
systemctl start --user pulseaudio.service

Now every application is pointing to the right device.
