It appears you did not follow the guide... (AppleHDA not loaded).

Can you point me a direction to search about this?

Just one question:
Is this normal? (I have audio activated on bios, and it works on windows)

 

[ruilopesdasilva]

I've run the tuturial again and now I get KP when I plug/unplug the cable

You can take the HDMI part out by changing the patches slightly (to keep DP connector type 00 04 00 00)...

and

About the patches, how do how I know which should I activate?
Is this correct? the Graphics Node:

It depends on which port your external monitor is connected to.
If you don't know enable both 0105 and 0204.

I've been trying to put this to work, but still no success..
I've ssdt-igpu from you thread with the scripts for the probook.
I've notice that this ssdt-igpu.aml has preference over the config.plist, in clover, right?

I've checked my work using this thread: https://www.tonymacx86.com/threads/...-dp-audio-sandy-ivy-haswell-broadwell.189495/
I found out that all is correct.


My Question is even without HDMI audio appearing on the audio preferences the display port should work?
I'm facing an error with the AppleHDAController.kext,
The following symbols are unresolved for this kext:

kxld[com.apple.driver.AppleHDAController]: _gAudioStackDebugFlags

is this causing the issue??

Thanks
I've been search for answers but i'm still unable to fix this issue.

Nothing to do with Clover, but yes, ACPI injection via _DSM does override anything injected by EFI (as Clover Graphics/Inject uses).

The ProBook guide provides all the correct patches for HDMI audio/HDMI video.

HDMI/DP audio only appears after you plug in an HDMI/DP device.

I'm facing an error with the AppleHDAController.kext,
The following symbols are unresolved for this kext:

kxld[com.apple.driver.AppleHDAController]: _gAudioStackDebugFlags

Somewhere along the line you installed a corrupt or incorrect kext. Run the OS X installer to refresh your kext.

I've reinstalled OSX and followed your probook guide, and now I finally have audio working and the device is showing in the system preferences:


But I'm still facing a KP when I connect the Displayport cable (Not HDMI, I don't have HDMI port)
I'm wondering if I have to use the patches in:
KernelAndKextPatches/KextsToPatch in config.plist, with the dsdt files (will this work)


Here are my logs once again, thanks for you support

 

[ruilopesdasilva]

I finally was able to put display port working..

After clean install of your probook guide, had to change on IGPU DSDT the device id to 0x0D260007

Thanks for everything
