Hi all, I'm stumped, maybe someone can help. Much thanks in advance, I want to use my computer for video work so HDMI audio is essential.

• Description of HDMI audio problem
  • The install works correctly, after restart no HDMI audio is available.
• OS X version/motherboard model/BIOS version/processor/graphics
  • Sierra 10.12.4
  • Dell T3600 motherboard
  • Latest BIOS (v12 I believe)
  • Intel Xeon quad core
  • Sapphire AMD Radeon HD 7870 2048 MB
• Procedure/Guide Used
  • I used the latest version of the script, here is the output:

File: audio_cloverHDMI-120.command_v1.0d

Release Mode

no HDMI audio

ssdt is working, problem is framebuffer connectors do not match physical connectors.
Fix: (select one; remove before attempting other method )

1. Use default framebuffer/remove Clover injection
   1. set config,plist/Graphics/
      1. FBName, remove
         
      2. Inject/ATI/NO
2. Edit AMD7000Controller.kext/Futomaki frambuffer
   1. see Post #1/Requirements
      1. S/L/E/AppleHDA.kext
      2. Graphics
         1. Intel HD Graphics
            
         2. AMD HD5xxx/HD6xxx/HD7xxx/R7-R9 2xx/R7-R9 3xx
            1. AppleHDAController and .....

OK so for some weird reason i am getting KP whenever i update anything further than 12.1 so i will try to make this work and then tackle the update KP ...

When you say Save/install/restart what do you mean to reinstall????
If i run the terminal command again the terminal will patch the config.plist/KernelAndKextPatches/KextsToPatch/Item 1/t2-10.12-SKL-1912000-4_displaysand put it back into the config.plist
Also i am using Plist edit Pro not sure if Xcode is really needed i dont have it installed

TIA

Edit : since terminal put the patch back on I decided to delete the entry from the .plist and run everything without using the terminal command... here are the files

Edit 2 : Found the solution to avoid KP in 10.12.5 i was missing the FakePCIID_Intel_HDMI_Audio.kext now we can further debug with 10.12.5 but i am still having no HDMI audio Attaching the new files with 10.12.5

I do not see reinstall, except, in your reply.
Save/install/restart means save config.plist, install edited config.plist, restart with edited config.plist installed.

Running the script was not mentioned; no support for incorrect assumptions.

Removed both patches. Download your config.plist from Post #2955 and follow Post #2956, exactly.

Thank you toleda, option 1 worked. I have to run more tests in the morning to be sure, but my monitor now shows up over HDMI. Wow, that was easy!

Not correct, try again.

Am I missing something ???
it seems to be corrected ..... I am not seeing anything with
config.plist/KernelAndKextPatches/KextsToPatch/Item x/10.12-SKL-1912000-4_displays (2x) or
config.plist/KernelAndKextPatches/KextsToPatch/Item 1/t2-10.12-SKL-1912000-4_displays

Yes, the screen shot is not correct, same as the incorrect config.plist..
