Can't enable internal microphone

[Blackeye42]

Does anybody know anything about the external mic? I have a 2 in 1 jack for headphones and mic. Internal mic works fine but the external doesn't.

Combo jacks are tricky. They have been made to work for certain codecs, but others are stubborn.
In any case, requires correctly patched AppleHDA...

As one example I know that was made to work with the help of Mirone, as noted in README.txt in the Probook repo:

Note regarding ALC280 combo jack and difference between original and for G2.

From Mirone: http://www.tonymacx86.com/el-capita...k-g2-alc280-combo-jack-wip-7.html#post1242688

To the kext to ALC280 of @zirkaiva I had to add in: Headphones/MuteGPIO=4 in Layout-ID, to your Headphone work, to be honest this is an exception for most the ALC codec for Laptops works without it in Layout-ID, and this is your case I should have tried the first time, When you said that ALC280_Original worked, least headphones. We have two slightly different scenarios, the first in which HP Elitebook 9480m Folio need Headphones/MuteGPIO=4 in Layout-ID, for your Headphone works and the second where HP Elitebook G2, not must have these values in its Layout-ID so your headset work correctly, RehabMan keep this in mind when updating your repository.

When we tried the same idea with ALC283 on my u430, we were only partially successful, and I haven't bothered to look into it further (lack of long enough block of time to take a serious look at it).

I didn't get it right. Did he change the layout-id from 3 to 4, causing the disable of internal mic and enable external one? Should I make any changes to AppleHDA? In any case I use layout-id = 13 with this kext https://github.com/insanelydeepak/Patched-AppleHDA-for-Mac-OS-Sierra-10.12

You will have to read through the entire process at the link I provided. And you will need to investigate how the changes made might relate to your own codec. Don't expect it to be easy.
