I have a ReSpeaker 4mic version. kws_doa.py Channels changed to 4 vad_doa mic_array.py test_4mic() enabled and disabled test_8mic()

Most command's give an error: google_home_lights.py: No USB device found.

That last one is a real issue. Drivers are installed but also I can't record from this device. pi@retropie:~/mic_array $ arecord -L null Discard all samples (playback) or generate zero samples (capture)

Do you have other applications, such as pulseaudio, using the recording ALSA device? You can run echo 'autospawn = no > ~/.config/pulse/client.confto disable pulseaudio autostart, runpulseaudio -k` to kill pulseaudio.

The script uses ac108 alsa device. Try arecord -f S16_LE -r 16000 -c 4 -D ac108 -v s.wav to test if the ac108 alsa device is available, then run the script.

I have a similar problem

Recording works fine on using arecord, and I am not using pulseaudio.

I don't see a108 is only for capture however
