No Audio Devices - AppleHDA Realtek Audio

Hi,

I am currently using an ASUS TUF Z390M-Pro Gaming (non WiFi) motherboard running the latest Mojave 10.14.6 using the vanilla method and everything is working perfectly... except Mic input. Used this Vanilla Guide as my starting point.

MB BIOS version: 2401
CPU: Intel i5 9600k
GPU: Intel UHD Graphics 630 1536 MB

My motherboard uses the S1200A audio chipset and only has 3 physical back ports (blue, green, pink) so set my config up to use "layout 3".
Output works perfectly via the front and back green jacks and even over the DP and HDMI ports.

The problem is input! No matter what layout I use (1,2 or 3) the Mic port front or rear is no good. (tried "Line In" as well but no good)
Layout 3 seems to be the closest if I use the rear Mic jack and turn the mic volume to the max the Mic works (barely) but there is so much hiss and static it's unusable.

AppleALC.kext is what's different
See Mojave AppleHDA Audio/Post #19
Differences:
a. ALC892
b. Procedures/3. Manual Speaker and Headphone selection
Thanks for the help Toleda. I wasn't able to separate the speakers and headphones, but I read on another post where you were helping with a similar issue. All I had to do was switch it to Layout ID 4 with your updated AppleALC kext and it fixed my problem for ALC892. Thank you for the help.

One problem is the purpose of each Audio ID; 2 disables Mic/Rear/Pink and repurposes to Line Out/Rear/orange; do not use
1 and 3 work the same, except 1 shows Line Outs (Black and Orange) that don't exist
See AppleHDA Realtek Audio/Post #1/VII. Audio IDs/Layouts
Audio ID: 3 is configured correctly and working
Make and model of mic?
 
  1. Updated to 10.14.6 Supplemental and the on-board audio - All working fine before. No other changes noticed (USB ports still OK, sleep OK, etc) Audio still works via Displayport and my monitor...
  2. 10.14.6 Supplemental/ASRock Z370 Extreme4/Latest/8600K/RX580
  3. AppleALC originally - Updated all the kexts, changed the audio layouts - No difference.
  4. See attached.

Thanks for taking a look toleda,

I'm using a pair of Xiaomi Hybrid Pro headphones with Mic (they work fine on my MBP) I've tried 2 different 3.5mm 4 Pole Splitter cables as well but still no difference. This is a complete assumption but it seems like some kind of amp or lack there of issue.

*** Edit **
Reading the git comments on the ALCS1220A (not S1200A) chipset. I thought the issue might be similar to Layout 11 but I could just be talking crap. I'm not experienced with OSX system internals. I'm actually a Java developer :D

Remove FakePCIID-Intel-HDMI-Audio.kext and FakePCIID.kext
Restart, reply with new files.

Thanks.

Deleted them, rebuild the kext cache, used onyx to cleanup all the other caches and rebooted - fixed.

Try the splitter with a 3.5 mm mobile phone headset.

The developer of 1220/Layout 11 retired years ago. Surprising to see someone else messing with another developer's work. The protocol is to apply modifications to a new layout id with source credit.

The Xiaomi Hybrid Pro headset is a mobile phone headset. I've tried a few other phone headsets too and they all have the same issue.

The mic does 'work' if I hold it right up to my mouth and have the input volume in the Sound system preference maxed out. But if the mic hangs where it normally does you can barely hear me. I only have they volume at 50% on my MBP as a comparison and that is loud enough. If I try turning the "ambient noise reduction" off the static is louder than my voice.

Thanks again for your time.

*** EDIT***
My SMBIOS is set to be a Macmini8,1 could that have anything to do with it? I seem to get graphical glitches if I use something else.

Cheers,
Isaac
