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"> MIC2: Code: <path name="media-headset-mic"> Can someone try to set those in alsamixer and report back? I dont have a PB with me atm...
Come have a chat in the Pine IRC channel >>

I'll try to find some time later today to fiddle with this, but when we had a look last night, I got one of internal mics working by just toggling the LADC input Mixer MIC1 boost Switch as it was off (one of the settings near the end in alsamixer in the playback mode) and the other 'just worked' when I plugged in a TRRS/four pole headset (and no, it wasn't the internal mic on the headset, I did check). However, I'll report back, and we can put together a post to pull all this info together in one place.
