System information

Windows 11 Pro; godot 4.3-stable 4-Channel Microphone Array

Issue description

trying to run the audio\mic_record sample on an ASUS laptop with a 4-channel microphone array produces no audio when recording, and throws the below error multiple times:

E 0:00:05:0391   thread_func: WASAPI: unsupported channel count in microphone!
  <C++ Source>   drivers/wasapi/audio_driver_wasapi.cpp:855 @ thread_func()

Steps to reproduce

Run the audio\mic_record sample on a machine with a 4-channel microphone array input device.

The Driver only caters for 1 or 2 channels for input.

I believe there's a feature proposal for this.

I've tried with a 2-channel input also, and it didn't work either.

I've tried with a 2-channel input also, and it didn't work either.

Does it print any error in this case? Try adjusting the sample rate as well to 44100 Hz or 48000 Hz.

It doesn't print an error in the 2-channel case, I have tried switching to 48000 Hz.

I have come across this forum post of other users also experiencing the same issue.
