Not the UCM, then.
It seems from the dump that the Wireplumber client hasn't started any
services to discover the hardware. The Wireplumber client here has,
"session.services": "[midi, policy.linking.role-based,
bluetooth.midi, audio, api.libcamera, api.bluez, policy.device.profile,
api.alsa-seq, api.alsa, video-capture, policy.device.routes,
bluetooth.audio, policy.linking.standard, policy.default-nodes,
api.v4l2]",
The following script is responsible for populating that,
/usr/share/wireplumber/scripts/session-services.lua
Does it exist there? Is it being loaded by
/usr/share/wireplumber/wireplumber.conf?
Please attach your local wireplumber config,
tar czf wireplumber-config.tar.gz /usr/share/wireplumber
/etc/wireplumber ~/.config/wireplumber
Maybe there's a bug in the upgrade path, or some local configuration
interfering here?
