MIC detect and analog volume control are mutually exclusive so you have to choose one or the other.I recommend configuring the DAC3101 to trigger an interrupt (see P0R48/R49) to your uC when it detects...

AIN1 and AIN2 have an input impedance of >10k. You can use them as line inputs (make sure that you AC couple the input signal as they are both biased to AVDD/2).

View ArticleForum Post: RE: tlv320aic3104 HPF pole calculation for speaker out
Assuming your amplifier has a high input impedance, you won't see much of a drop in your output signal. With the AIC3104 it is possible to DC couple the HP outputs so you wouldn't need a series cap. If...
