BUG FULL_05: Optional input amplifier: gain is too low
=== BUG FULL_05ALL_01: Optional input amplifier: gain is too low Missing 1V8 26MHz Oscillator ===
'''INFO:''': Gain from NFM2173 isn't enough for a MIC audioThis clock is not mounted at proto first assembly. It is necessary to enable some PLL and other PXA2128 clock subsystem.
'''WORKAROUND:''' Use PMIC MICs as Installed a dedicated input for a JA1 connector: disable optional input amplifier, input audio switch and cirrus U81 ADC1 and ADC2:1V8 26MHz Oscillator with 50 ppm from "XTAL affaire box"
