System: 10.12.6

I didnt know my audio codec name so i get it by AppleHDAPatcher app - Realtek ALC255.
I tried to use VoodooHDA before, but sound is so quiet sound, that's why i decide to use AppleALC+Lilu (last versions).

Problem:
i start to change layouts:
3 - crackling;
13 - crackling, microphone dont work;
17 - crackling;
18 - speakers instead headphones;
27 - good sound (without crackling, not quiet), but in input devices 2 microphones - both dont work;
28 - clean but quiet sound, micro work;
99 - crackling, no micro.

Its possible to get Output device from layout 27 and Input from 3? (for example).
Thx.

Would require custom XML.
You might read the AppleALC wiki with regards to new codecs/layout-id.

Fixed.
I changed values for ADC in files "Platforms27.xml.zlib" and "layout27.xml.zlib" of codec ALC255.

Ctrl+C gray block
Ctrl+V blue block

[For newbie] If u decide build ur own AppleALC.kext be sure that project folder include Debug version (not Release) of Lilu.kext

You should probably submit as issue or pull request to the AppleALC project on github.

Marking this thread as solved.
