I kinda remember having similar issues years ago, when transitioning from Pulseaudio to Pipewire on Ubuntu based distros like PopOS.
A bad guess is that either pipewire-pulse and pipewire-alsa was missing or I changed wireplumber to the other thing. I am very unsure, but it was a huge mess to play around and constantly switch between pipewire and pulseaudio to test things.
Didnt AFD won in the East of germany? The extremest right party that called Hitler a left wing?
