activate microphone?

I did it before on Pine64 boards, configuring the codec in alsamixer is a bit complicated because it has 113 controls. Looking at the PB schematic MIC1 is wired to the internal MIC and MIC2 is wired to the headphone jack for 4 ring connectors. I'll see if I find some time tonight to play with the settings... it works on Android so the hardware should be good

Looking at what Android does:

MIC1:

Code:

 <path name="media-main-mic">
   <ctl name="AIF1OUT0R Mux" value="AIF1_AD0R" />
   <ctl name="AIF1OUT0L Mux" value="AIF1_AD0L" />
   <ctl name="AIF1 AD0R Mixer ADCR Switch" value="1" />
   <ctl name="AIF1 AD0L Mixer ADCL Switch" value="1" />
   <ctl name="ADCR Mux" value="ADC" />
   <ctl name="ADCL Mux" value="ADC" />    
   <ctl name="LADC input Mixer MIC1 boost Switch" value="1" />
   <ctl name="RADC input Mixer MIC1 boost Switch" value="1" />
   <ctl name="ADC volume" value="180" />
 </path>

MIC2:

Code:

<path name="media-headset-mic">
   <ctl name="MIC2 SRC" value="MIC2" />
   <ctl name="LADC input Mixer MIC2 boost Switch" value="1" />
   <ctl name="RADC input Mixer MIC2 boost Switch" value="1" />
   <ctl name="ADCL Mux" value="ADC" />
   <ctl name="ADCR Mux" value="ADC" />
   <ctl name="AIF1 AD0L Mixer ADCL Switch" value="1" />
   <ctl name="AIF1 AD0R Mixer ADCR Switch" value="1" />
   <ctl name="AIF1OUT0L Mux" value="AIF1_AD0L" />
   <ctl name="AIF1OUT0R Mux" value="AIF1_AD0R" />
   <ctl name="ADC volume" value="160" />
 </path>

Can someone try to set those in alsamixer and report back? I dont have a PB with me atm...
