After the latest slowroll release (including the update to Plasma 6), my laptop
no longer switches between HDMI audio and internal speakers when an external
display is connected/disconnected.

I have to e.g. when disconnecting HDMI, manually go into Plasma sound settings,
show inactive devices, and switch profiles to Analog Stereo Output.

To be clear – audio works both with laptop speakers and with HDMI, I just have
to manually switch profiles. This is very annoying.

Things I’ve tried:

    Reinstalling pavucontrol, pipewire-pulseaudio, wireplumber
    Removing ~/.local/state/wireplumber
    pactl load-module module-switch-on-connect

This also happens under the latest 20240409 Tumbleweed KDE Live image.

However, reverting my actual install to a previous snapshot restores my
laptop’s ability to automatically switch between internal speakers and external
display (HDMI) audio.

Obviously this is not a long term solution as I cannot update without losing
functionality. I also do not have this problem on the latest KDE Neon live
image. It seems to be limited to openSUSE.
