Hi,
I am also trying to use MIC, and speakers; but did not get any output yet. I installed pulseaudio, and followed your procedure but no luck. Could you please explain how exactly I can use MIC and Speakers on NanoPi NEO Air? Have you used those 4 solder pads on board to attach hardware or got any success from GPIO? If you have used solder pads, then explain the MIC P / N pads, as no guide is given to identify which solder pad belongs to which pin. Please guide me.
