Iemand anders had het met zn bluetooth koptelefoon. Zou dit ook voor mij werken?
This is a bug (pulseaudio #832, launchpad #1866194) with new version of pulseaudio in Ubuntu 20.04 where old config values have not been cleared and it is not routing to the correct device. The solution is to delete the old config and restart pulseaudio:
Open a terminal (Ctrl+Alt+T) and run the following commands:
mv ~/.config/pulse/ ~/.config/pulse.old
systemctl --user restart pulseaudio
A pulseaudio fix #298 is currently in progress.
