Hi there, :slight_smile:

I am new to the Banana Pi Forum, But, got enough experience to deal with U-Boot compilation to get Arch Linux ARM booting and running from BPi Pro, BPi-M1 and BPi-M3-A83T.

Today, I am curious to learn about the “built-in” microphone present on those SBC.

Can anyone share reliable pointers on Internet to save days of research to just find answers to these questions, please:

  1. Is that microphone really operational ?
  2. How to utilise it under Linux ?

Thanks in advance ! :wink: :slightly_smiling_face:

Best regards, H.P.
