Hey guys!
I try now since yesterday to bring OpenWakeWord or Assist on my Home Assistant to work. I tried to fix this issue with ChatGPT first, but it seems this AI is overwhelmed with that. 
Problem
OpenWakeWord doesn’t recorgnize any wake word. Piper, Whisper and OWW is correctly installed and connected to Wyoming Protocol.
OWW only connects and disconnects like in the log shown and flooding it with it:

The USB microphone works very well with Rhasspy and is set as default recording device in HA.
I also looked into the /share-folder and there’s no openwakeword-folder. OpenWakeWord also tells me nothing about an audio device.
