    Hi Lawrence,

    Everything looks fine except for the MICBIAS connection. Typically only the positive side of the microphone needs the MICBIAS while the negative side uses a resistor to GND to bias the negative side. Double check your microphone datasheet and refer to Figure 188 in the AIC3109 datasheet.
