Using Ubuntu 23.04 with Gnome 44.1.
What does this lock with a warning triangle mean? No tooltips appear when hovering and none of the system menu entries show anything. I cannot find any documentation on Google.
This is on a machine I upgraded from 18.04 to 20.04 a few days ago. No issues at all getting sound to play out of headphones on 18.04.
The headphones are paired with Bluetooth. I unpaired and repaired them just to be sure. The settings panel for sound has them as an output option and I can select it without issue. However, no sound ever comes out of the headphones. I've even adjusted the volume both in the settings panel, in alsamixer and in pavucontrol. Nothing changes.
I see no errors in the bluetooth service log.
Output of:
