Hello,

 

The reason is that the audio codec that the board has, doesn't support any audio input. For that reason, the gstreamer pipeline can't open the audio card. The only way to record audio is through software, for that I recommend you to use a USB microphone. I apologize for the inconveniences.

 

Best Regards,

Diego.
