[fuyao]

Hello everyone, following the work of the audio codec in v3s and h3 I have created some patches for r40 in armbian. These are working although the bananapi m2 berry patch has added the microphone path which does not exist (you have to update). if the patch is correct whoever wants can continue and send it to mainline.
