Update breaks sound

After updating, I can’t hear sound anymore, and the icon in the KDE bar has a “no sound” (like ø) symbol, and I don’t see any audio devices (also none in pavucontrol).
The problem is reproducable: I just restored a one week old snapshot (after which the sound was working), updated, rebooted, and the problem is back.

I see problems in the log:

$ journalctl -e -b | grep -i audio

AVC apparmor=“DENIED” ?

Huh. Interesting. How did this ever work?

you have setup apparmor or not?

Yeah, sure. I’m currently working on fixing it. I was just wondering how I ever had sound, because I didn’t change the apparmor config.

And it’s working again. Thanks!
