PS I will post again if you want the basic low down on audio engineering for arrays.

Not sure the module for the ps3-eye presume its snd-usb-audio but cat /proc/asound/modules when plugged in and again when ps3-eye unplugged will tell you that one on the host. Options snd slots=snd-usb-audio,snd-bcm2835

Sudo nano /etc/modprobe.d/nf on the host options snd_usb_audio index=0 I tend to be a bit OCD so I do this just to get a better soundcard order. If you are using docker then remember to connect to the container. It should still work though and should list but now that RaspiOS defaults to pulseaudio depending on if you use the desktop or lite version and if you arecord or pyaudio it may or not work. Its just one of those PC myths that because its an array its any good, it was really good but that was the Sony software that was in the PS3 not the mic. Its debatable if the sum of the channels is an increase over the sum of the SNR which will happen and also side on it forms a high pass filter. That still doesn’t explain why its not recognised as the drivers are not great but they do work even though they are a reverse engineer hack that have had the same niggles for over a decade. Its sort of pointless as the beamforming algs to make it work where in the PS3 eye.
