Greetings all,
I have been having issues trying to get Voice Assistant and Open Wake Word working and I’m not sure where to look next.
This is a fresh install using Raspberry Pi Imager - V2.03 (Home Assistant OS 16.3 (RPI 5))
Hardware
Raspberry Pi 5 (Rpi5-64)
64GB Max Endurance SanDisk microSD
USB Audio Adaptor with 3.5mm microphone input and speaker output. I have plugged in a known working microphone to the device (ie tested and confirmed working with windows Voice Recorder).

I followed the instructions per Wake words for Assist - Home Assistant
Working through the Troubleshooting Assist - Home Assistant
I can successfully run a text command and have it control my devices.
I did notice that clicking Start Conversation from the three dots beside my Assistant, the microphone icon has a red !, clicking it just shows [object, object] which seems odd…

I also note, I can play audio files via the connected USB speaker using MPD without issue.
Not sure what to check next, hope someone can give me some direction.
Other settings:
Thank you
