Hello bugsounet, unfortunately, nothing has changed. The file is still not present and the recording worked and was played back. After deactivating the modules, the MagicMirror just stays black and I can no longer reach the gateway

admin@raspberrypi:~ $ cd ~ && cat .asoundrc 
cat: .asoundrc: No such file or directory

admin@raspberrypi:~ $ arecord -D default -q -r 16000 -c 1 -t wav -f S16_LE -d 3 test.wav && aplay test.wav

Hello bugsounet, tried what you wrote, the file .asoundrc does not exist and the recording started and played back without error.

cd ~ && cat .asoundrc 
cat: .asoundrc: No such file or directory

Thank you very much for your support, unfortunately I can’t work on the mirror again until Monday. I will try and post the outputs on Monday

Here are the outputs

I had no intention of changing the micro configuration. The voice input did not work and then I came across the warning in the gateway terminal output. I just wonder why the voice input does not work. I have installed and configured everything according to your instructions. When I make a request to google via the gateway tools, it is answered and displayed on the mirror.

Hello bugsounet, first of all many thanks for your great work. Do you have any idea where the problem could be? The google assistant does not respond to any voice input. In the terminal output of gateway there is a warning from arecord(screenshot1) every second. As I understand it does not find the micro. So I started looking for the device name in your files and found the following entry in three files:

/MagicMirror/modules/EXT-Detector/components/porcupine.js
./MagicMirror/modules/EXT-Detector/node_modules/@bugsounet/snowboy/index.js:
./MagicMirror/modules/EXT-Detector/node_modules/@bugsounet/snowboy/sample.js:

device=“plughw:1”

When I tried to start a recording with arecord --device =plughw:1 --format… I tried to start a recording and got an error. So I searched for my device name, it is “plughw:2,0”. At least I can start a recording with arecord --device =plughw:2,0 --format…(screenshot2) and record sound. After I have adjusted the entries in the three files (screenshot3), unfortunately the message still appears and the voice input still does not work. Maybe you have an idea what else it could be?
