題目: [DNG] Soundsystem mostly disappears in KDE Plasma on upgrade to Daedalus
Hi

After an upgrade to Daedalus, KDE Plasma's list of audio devices is empty
(settings -> audio -> devices). The output can't be selected. Before the
upgrade audio was working perfectly (using pulseaudio).

Playing sound from VLC, Audacity and some others does work, but only through
the internal speakers. No other output can be chosen. The volume can't be
changed from the system tray's speaker symbol.

To try to fix it I replaced pulseaudio with pipewire. This did not fix it
permanently, means: Sometimes after a reboot the devices get listed in KDE and
output choices and volume settings are working, but mostly the list is empty.
I did not find a way to fix it permanently (unplugging the external monitor
and all USB for example).

Does anybody know a solution for that?

Thank you very much.

Regards, Adrian.

PS: The Laptop has Intel HD Audio and some nvidia hardware, it's a ThinkPad
from around 2012 with dual graphics (discrete and integrated). I am not sure
why the nvidia hardware is relevant for audio, but I can see it in amixer,
maybe for HDMI output or so. The problem can be found searching the net, but
there are no general solutions that worked for me.
