Unfortunately not sure what could be the reason here, but most likely a misconfiguration of your Linux setup. We can't provide linux support (too fragmented when it comes to custom distri) but there is a starting point here: www.minidsp.com/applications/usb-mic-arr...a-8-google-assistant

You should look at the PortAudio cross-platform, open source, audio I/O library.

I have used it successfully to record and play audio from a Raspberry Pi 4.
