WirePlumber 0.5 – How to enforce priority-based auto-switching?

Help
1

I’ve set custom priority.session values for my sinks (e.g., dock > internal speakers). Auto-switching works — until I manually select a device from the KDE tray.

Once I pick something in the tray, it becomes the “configured default,” and priority-based switching stops. You can see this in wpctl status:

Settings
 └─ Default Configured Devices:
     0. Audio/Sink alsa_output.pci-0000_00_1f.3.analog-stereo

WirePlumber stores this in ~/.local/state/wireplumber/default-nodes. Clearing it with wpctl clear-default restores priority-based switching — but KDE can overwrite it again.

Question: How can I make WirePlumber always respect priority and ignore user-selected defaults, for fully automatic switching?
