System Tumbleweed KDE Plasma was updated today 9th October 2024 using zypper
dup and on restart the following happens every time.

When using KDE System Settings Sound or the Audio Volume widget I get this
error

file:///usr/share/plasma/plasmoids/org.kde.plasma.volume/contents/ui/main.qml:21:1:
Cannot load library
/usr/lib64/qt6/qml/org/kde/plasma/private/volume/libplasma-volume-declarative.so:
/usr/lib64/qt6/qml/org/kde/plasma/private/volume/libplasma-volume-declarative.so:
undefined symbol: _ZN12PulseAudioQt7Context12stateChangedEv

Sound works OK just cannot adjust it using these options.
