I think it is because you can tune the variables now via the tuning.py. These settings are however not saved on the device itself. So a powercycle sets them back to default.

I use this on startup:

python3 usb_4_mic_array/tuning.py -r
python3 usb_4_mic_array/tuning.py AGCMAXGAIN 31
python3 usb_4_mic_array/tuning.py AGCGAIN 31
python3 usb_4_mic_array/tuning.py AGCONOFF 0
python3 usb_4_mic_array/tuning.py -r

But it sucks. See:

setting these values persistent across reboots would be awesome
