I try every layout-id, use latest lilu+applealc, but still can't get microphone (pink) to work, it just white noise , even i plug my mic or not. Im on Desktop, not Laptop.

 

So far i use alcid=16 it better because it show more output (headset/speaker,etc), but it still not getting microphone to work.

 

On system preferences > sound > input, it shows

  • internal microphone
  • line-in

My motherboard doesn't have internal mic, unlike laptop. Is this the reason?

Btw, This is my setup:
CPU: Intel g3260 (haswell)
GPU: Nvidia Quadro 600
Audio: Realtek ALC662
OS: Mac OS Sierra 10.12.6
Bootloader (uefi): Clover r2114

 

Why i not update to higher os? Because my hardware is old and graphic card just support in osx sierra. I use this os just for audio/music/daw things. (Garageband,etc)

 

If i switch to opencore, is this somewhat fixed? If yes, what the config to add?
