I have installed Plasma 6 from the KDE repos. It works great (though the upgrade process was a pain, but I expected that). After upgrade, the issue I’m having is that there is no volume control icon in the systray. It also isn’t hidden (It’s not even an option in systray settings). I attempted to raise this in the KDE forums, but they suggested that it is more likely a repo/dependency problem on openSUSE.
Any help would be appreciated.
If you right click on the arrow (system tray) > ‘Configure System Tray…’, do you see it listed to choose from?
I have Krypton running in a VM, and the volume control is visible in the tray.
Looking at your first screenshot, it doesn’t look like you’ve scrolled upwards enough (to the top / beginning of the list)
Is ‘plasma6-pa’ installed?
Yup, that worked. Thank you. Apparently, when upgrading, it didn’t pick that up. plasma5-pa was still installed
Glad to have been of guidance. 
The name of the fix sounds suspiciously like a dependence on pulseaudio remains in Plasma6, instead of it acquiring pipewire/wireplumber sufficiency. 
Anyone here know if my supposition is wrong?
Yes, I think it still relies on the PulseAudio API for that widget.
Just to clarify further - having the ‘pipewire-pulseaudio’ package suffices for the backwards compatibility (as opposed to requiring PulseAudio itself).
