Are we at the end of the road for S1200A?
Not yet.
Questions:
Dual Boot?
If yes, Realtek driver installed? If yes, remove
If no, need a way to confirm codec is working (Windows, Ubuntu, etc.)

Verify exactly one version of AppleALC.kext is installed; debug log shows almost 300 codecs when the 1200A AppleALC has 4 codecs.

Try a cold boot; power down, pull power cord, hold power button down for 30 seconds (ensure all motherboards LEDS have turn off), restore power cord, boot
Reply with new IOReg (last AppleALC, either layout)

1.3.4 Debug from post #70 worked for me on a build I'm doing for a friends son.

macOS 10.14.2
Board: AUSU ROG STRIX B360-F Gaming
Audio Codec: S1220A

In macOS 10.13.6 I also got the codec working by rolling back to older versions of AppleALC and Lilu. (included in EFI attached EFI/Clover/Kexts/10.13)

Working EFI folder and IOReg of the system attached.

S1200A sound works in Ubuntu 18

debug log shows almost 300 codecs when the 1200A AppleALC has 4 codecs.

Don't understand. Only one AppleALC kext file in /Library/Extensions - no AppleALC kexts in kexts/Other

Would it help to reinstall HS 10.13.6?

Will report back after cold boot sequence. New log script noted.
 
Expected.
This thread is for the S1200A not your S1220A

Oops, you are right. (my eyes kept seeing S1220A) Either way latest release 1.3.3 dd not work and some of the other 1.3.4 you posted a few posts back did not work either except the one from post #70. So thanks for the help.

Could we expect the same results from release of 1.3.4? Is it ok to keep using the Debug version you provided?
