Forum Post: RE: TLVAIC3101 microphone detection

Hello,

   Thanks and please help me at your first convenient time.

   Here I have some update these days.

   I tested MicDet function on TLV320AIC33 EVM board and it work quite well.

   However, I did notice there are slight different on AIC IC side,

   I mean, there is a independent MICDET pin (pin12) on AIC33, and it's bind with MIC2L on AIC3101.

   I'm not sure it's a factor or not.

    My AIC3101 always reports that "there is mic plugged!!".

    Do you need my schematic snapshot? or any suggestion on Reg setting?
