How to correctly configure the microphone. Default config doesn't pick it up?

denis4o

Hardware:
Raspberry Pi 3b+
Raspbian 11 (Debian 11 bullseye)
USB microphone

Issue: The Detector starts normally however, I believe that the USB mic is not correctly selected as no hotword is picked up.

I can record and play wav files via:

arecord --format=S16_LE --rate=16000 --file-type=wav out.wav

aplay out.wav

EXT-Detector is a plug-in so what MMM-GoogleAssistant wiki says?

denis4o

@bugsounet got it! Thanks. I was coming from MMM-GoogleAssistant v3 with a separate Snowboy module thus the confusion. Now everything is working.

Solved How to correctly configure the microphone. Default config doesn't pick it up?
