Pipewire or wireplumber not remember last routing

I set routing with pavucontrol, Seren VoIP client via echo cancelation module. It does not remember the signal path during the next boot.

Versions:

wireplumber-0.4.13-1.fc37.x86_64
pipewire-0.3.63-3.fc37.x86_64 (latest build from git repo: 9c2b2a64)
