Not what happened.
IOReg is missing
Used 3 methods to install audio, each on top of the previous, user error:
1. MultiBeast
2. cloverALC
3. pikeralphaALC
Audio failure is guaranteed.
Remove AppleHDA1150.kext
Restart, reply with new files

It's fixed. Thats all it took. I deleted AppleHDA1150 from both /S/L/E and /L/E. Restarted and it's working. Anyway to delete these files automatically using your scripts? You fixed my issue in 1 sec while I spent 6+ hours last night till 4am trying to figure it out. THANK YOU!!!

No, impossible to anticipate every user's incorrect installation procedure.
Main AppleHDA audio thread describes what is done and how to undue.
See Realtek ALC AppleHDA/Post #1:
a. II. Realtek ALC AppleHDA Scripts
b. Uninstall Realtek ALC AppleHDA

Yup. I followed those instructions last night. The instructions doesn't say anything about deleting AppleHDAxxx.kext. It says to delete AppleHDA.kext which I did ( I actually moved it to the desktop ) which caused me to loose video on reboot. Had to mess with video settings on clover boot screen to get back in and move those files back. Maybe the instructions weren't clear to me. Your reply was very clear and worked. Thank you.

Working through the options


2 Audio/ALC Injection (see Tools 3.)

1. Double click/Downloads/audio_codecdetect.command
2. Terminal/Shell/Export Text As. . .

File: audio_codecdetect.command_v2.1
HDMI audio codec(s)
Intel: 0x80862806
Onboard audio codec
Realtek: 0x10ec0899
OS X/10.12.2 Onboard Audio
Device: HDEF@1B
Audio ID: 1
Valid audio codec, audio device and Audio ID; audio injection is working
Finished


3 HDEF Verification/IORegistryExplorer (see Tools 2./1.)

1. IOReg/Search: HDEF - PRESENT
2. IF IOReg/HDEF present, see 3. Audio_ID verification

4 Audio_ID verification/IORegistryExplorer see Tools 2./1.

1. Verify layout-id:
   1. <01 00 00 00> valid, all supported codecs - Present

5 Audio Codec Verification/DPCIManager, see Tools 1.

1. 
   
2. Note Codec ID
   1. 10ec0899 - ALC898 - CORRECT

6 System/Library/Extensions/AppleHDA.kext Verification

All files in AppleHDA.kext are binary - Not sure what to verify here.

1. AppleHDA.kext can be the same as or earlier than the installed OS X version
2. AppleHDA.kext does not work if newer than the installed OS X version
3. Verify AppleHDA.kext version and codec name
   1. ALC885
   2. ALC887
   3. ALC888
   4. ALC889
   5. ALC892
   6. ALC898
   7. ALC1150
4. If codec is native, go to 4. Audio Codec Verification, above
5. If your codec name is not listed, your codec is not compatible.

instructions doesn't say anything about deleting AppleHDAxxx.kext

Is delete different from remove?
Link above/Uninstall Realtek ALC AppleHDA
"3. pikeralphaALC, remove:

1. L/E/AppleHDAxxx.kext
2. config.plist/.../KextsToPatch/AppleHDA (2x)"

Missing.
Recommend cloverALC (persistent) over realtekALC (run after each software update)
See Realtek ALC AppleHDA/See Post #1/Uninstall Realtek ALC AppleHDA/4. realtekALC Rename and install: Desktop/audio.../AppleHDA-orig.kext)
Run cloverALC, attach new files

Thanks for the tip!

I was in the process of uninstalling and did these:
config.plist/.../KextsToPatch/AppleHDA (3x)
L/E/realtekALC.kext
and then before I replace the patched AppleHDA with the native one I noticed that the audio started working. so I stopped there and now I am monitoring it to see if it will persist.

Where did you get config.plist?
config.plist is not useable, replace.
Run cloverALC, restart, reply with new files.
