Sound tab and volume icon disappeared and keyboard keys can't modify volume

raphiki · October 19, 2025, 2:57pm

I tried to fix the “connection to the sound service lost” in the sound tab. I ended up removing ,installing and enabling wireplumber, pipewire and piprewire-pulse. I’m not sure if i modified something else along the way.

My audio input and output still work. But the sound tab doesn’t exist anymore and i don’t have a speaker icon on the bottom right. Also i can change the volume via pavucontrol but can’t anymore with my keyboard.

System details if needed :

Operating System: Fedora Linux 42
KDE Plasma Version: 6.4.5

I noticed some errors with wireplumber and its interactions with pipewire but i don’t know if those are related to the missings things described above.

OK. I just updated to Fedora 43 and immediately found out that there was an issue with volumeicon. It was missing from the panel. However, it was running, but just not showing up graphically. So I started using alsamixer in a console. That works but is a bit clumsy. Well my son figured it out. He dumped a stack trace into Chat GPT and it came back that there was probably an issue with glycin. I also had an issue with thumbnails that turned out to be glycin related. He got it to work by preloading an older version of the library before running volumeicon. He got it to work on his computer and will do the same for my two computers tomorrow. But figured I would just let you know. He is good at solving things…

Update:

My son tried to fix the issue on my computer today and it did not work. So he filed a bug report. Currently I am using alsamixer to adjust volume. I don’t care for the clumsy standard volume control applet at all. Will report back if we get anything figured out. Not very happy with the upgrade at the moment but most things are working just fine. Already figured out the thumbnail issue as well…

Don’t know if this has anything at all to do with what you are going through but I felt I had to pass on the information anyway…

My son figured out that my issue was with bubblewrap. Applied the fix and all is well again.
