Comment (by Terry Su):

 Please check U24(SN74LVC1G66) Pin 4 MIC_AC#/DC signal is High or Low ?
 When this signal program LOW(Normal Mode), I measured the Codec input
 Pin(Pin 21) is 1.09V when Microphone Jack input 3.3V.
 When this signal High(Scope Mode), I measured the Code input Pin is 3.3V
 when Microphone Jack input 3.3V.
