[PinePhone] Audio switching after PhoneCall not working properly

PipeWire version: 0.3.43
WirePlumber version: 0.4.6
Distribution: Manjaro ARM
Kernel version: Linux Kernel 5.15.13

I'm having some issues with the automatic switching of audio profiles.
I narrowed it down to a WirePlumber issue, as Pipewire-media-session and PulseAudio bot work properly.
When we receive a Phonecall on the PinePhone the audio gets switched over to "Internal Earpiece" with audio profile "Voice Call" by the Callaudiod.
When the Phonecall has ended, the audio should switch back to "Internal Speaker" with the "Hi-Fi Audio" profile.

Problem: The audio after ending phoneCall stays on the "Internal Earpiece" device.

Expectation: Audio after phonecall should be properly handed back over to "Internal Speaker" device.

Why I think this is a WirePlumber issue:

• First of all because PulseAudio works properly
• Second: Also tested pipewire-media-session, which inhibits same experience as PulseAudio.

WirePlumber as a future replacement of Pipewire-media-session should at least give the same overall experience in my opinion.

Please let me know if I can provide you with any additional information/logs to investigate this problem. I'll be happy to help out any way I can.
