Hello, I made my microphone setup with microphone mce103 according to this scheme  pin 10 (MIC-BIAS) ..... 3 - 15V in scheme, pin 11 (MIC 1P) ....... NF, pin 12 (MIC 1N) ....... (-)   in alsamixer I have: audiocodec, mic1_2 audio capture mode. then I tried: arecord -i -f S16 -r 22050 test.wav and it saved this wav file (in attachment). I am not able to record audio, it records just noise as in attached sample.   What can be wrong please? test_.wav
