Thank you for the report. We will take a look.

By the way, from your report it looks possible that the microphone is working but that it is no playing back correctly. Did you try running the examples/io/audioin/levelmeter example? It doesn't play the audio but logs to the console the average power level of each audio buffer.

Thank you for your reply.
Yes, I tried the levelmeter example，And it ouput Average 30935 continuously，I also tried the examples/pins/audioin/wavserver example， and download the wav file，It's 6 seconds, It can be played,but no sound.

@mrcyan – thanks for the additional details. Much appreciated. We took a look and have an idea of what we need to do to enable the microphone.
