BUG FULL_05: Optional input amplifier: gain is too low

INFO:: Gain from NFM2173 isn't enough for a MIC audio

WORKAROUND: Use PMIC MICs as a dedicated input for a JA1 connector: disable optional input amplifier, input audio switch and cirrus U81 ADC1 and ADC2:

- C704, C705 not mount

- R718, R716 not mount

- R737, R738 not mount

- R705, R708 mount

- R870, R871, R872, C889, C890 mount

- R800 mount

- R802 no mount

RESULT:

- JA1: PMIC MIC IN

- JA2-6: CIRRUS
