OrangePiPC + Armbian embedded microphone issue

[Mr. Fennec]

Hi there, I am trying to build a voice assistant using OrangePiPc. This is not orangepi zero, but I am posting it here, because there is no subthread for orangepipc. OrangePiPc has an embedded microphone, but for some reason it doesn't work. When I run arecord, I get an input/output error. Any ideas?

 

 

Here is a board description: http://www.orangepi.org/orangepiwiki/index.php/Orange_Pi_PC

That is because this board is not supported, and you were posting in the supported boards section of the forum.
