That mic gain adjustment is in fact a post scaling by above factors (x0.5, x1.0, x1.5, x2.0) , of each captured mic voice data . Then ,that adjustment should be only used,to make mic gain fine tuning of the non distorted voice . But if the captured data is already distorted , due to too much mic sensitivity , or to close mic-mouth distance, or too loud voice , the ADC saturation , should be addressed by other means (ALC or Boost adjustment (*1) , or increasing mic-mounth cms distance , or reducing the voice loudness.)

If you want to know the audio codec IC of your device , you do not need to dissassembly the boards, just go to the "debug" -> peripherals menu , and you will see which peripheral device, you can explore, looking its register map values. In the audio block icon , you will see the audio codec IC name , mounted on your Portapack board : AK4951 or WM8731. (see annexed photo of both two devices) If you want to know the audio codec IC of your Portapack board, you do not need to dissassembly the boards, just go to the "debug" -> peripherals menu , and you will see which peripheral device, you can explore, looking its register map values.
