1. Description of audio problem

Sound on headphones is distorted, as if I'm using an old cable and keep insert and remove it



2. Specs:

OS Version 10.12.6

Mobo Z270x-UD5

I7-770k

Nvidia GTX 970



3. Method

Installed using multibeast - codec for 1120 + 100 / 200 series audio - got audio devices (mobo only)

Used audio_cloverHDMI-120_v1.0d.command - still no HDMI / DP audio

Tried quick fix method 1 - FakePCIID.kext + FakePCIID_Intel_HDMI_Audio.kext



4. File: audio_codecdetect.command_v2.2


HDMI audio codec(s)

Nvidia: 0x10de0071


Onboard audio codec

Device: Not supported

Realtek: 0x10ec1220

Name: Realtek ALC

Audio ID: Not supported

Current Audio ID: 1 (valid: 1, 2, or 3)

FIX, try:

1. https://github.com/toleda/audio_ALCInjection/tree/master/ssdt_hdef/

ssdt_hdef-1-with_ioreg/hdef.zip (or -2 or -3, select View Raw)

2. CLOVER/config.plist/Devices/Audio/Inject/1 (or 2 or 3)

I did this operations:

1- I removed S/L/E/AppleHDA.kext
2- I modify EFI/CLOVER/config.plist removing the three parts with AppleHDA as shown in the attached file
3- In L/E there is no realtekALC.kext but only RealtekRTL8111.kext. I don't removed any files
4- CloverALC -> S/L/E/AppleHDA.kext already removed in point 1


After that I restart and install in EFI/CLOVER/kext/Other

- the content of AppleALC 1.1.4 (AppleALC.kext and AppleALC.kext.dSYM) through copy and paste
- the content of Luli 1.1.7 (Lilu.kext and Lilu.kext.dSYM) through copy and paste

then I restart again

but in audio preferences I see always only Soundflower speakers

Do you want to see again all the reporting files?

 

[toleda]

Sound on headphones is distorted,

Audio devices present, off topic. Start new thread.

 

[toleda]

Yes

 

[tracert]

Yes

AppleHDA is not present because removed previously

Thanks

AppleHDA is not present because removed previously

Why? Instruction: remove 4 .zml files
Where does it say to remove AppleHDA.kext?
No AppleHDA.kext, no sound

Sorry toleda,

I understood in this procedure that was necessary to remove the file AppleHDA.kext or the others single files. Is for this reason that I ask you before how to ricreate the native AppleHDA.kext file.

MultiBeast 8.0+, remove:

1. S/L/E/AppleHDA.kext and install the native AppleHDA.kext
   1. or S/L/E/AppleHDA.kext/Contents/Resources/layout1.zml.zlib, layout2.zml.zlib, layout3.zml.zlib, Platforms.ml.zlib

BTW, now can I copy again AppleHDA in the S/L/E directory and proceed to remove only the 4 .zml files?

 

[toleda]

can I copy again AppleHDA in the S/L/E directory

Cannot Finder/copy kexts to system folders, use KextBeast

 

[tracert]

Cannot Finder/copy kexts to system folders, use KextBeast

Ok. I use Kextbeast and put again AppleHDA.kext in S/L/E
After that I removed the 4 zml files

Attached alla files after the operations described before and the restart
