AppleHDA HDMI Audio [Guide]

The script adds 2-4 codec specific files to AppleHDA.kext. If those files are not present, no audio.

Okay, that's what I thought. It does make some physical change to the file but that's it.

So, what happens when the HDMI 130 script doesn't download a new copy of the PEG0.aml?

The old 120 version showed the .aml file being downloaded. Where does it come from in this case? And why does it not appear despite having the compatible card and EFI mounted?

The audio_cloverHDMI script is for personal use only. Do not distribute
the patch, any or all of the files for any reason without permission.
The audio_cloverHDMI script is provided as is and without any warranty.

The script is updated for new releases (-120 to -130), the ssdts are not. ssdts are updated when a new feature requires an update. The installed ssdt will work with the new card. The script will not install anything if HDMI audio is enabled.

I see, so maybe I should disable it. But removing that .aml doesn't remove all the settings. BTW, I tried the latest VoodooHDA and three HDMI settings showed up as expected for this card. But I could only hear a soft hiss through my headphones. So, I have gone back to AppleHDA sound. I will wait for my new DP cable and see what happens.
 
Hi toleda ,I have an asus b250m mainboard and a NVIDIA Quadro P600 video card(with 4 minidp ) working on 10.12.6 . I want my 4k display make a sound with its built-in speaker.
I looked into the post where you have a try,without luck ,I failed.
Here what I did:
1.Mount EFI
2.Download "audio_cloverHDMI-130_v0.6.command"
3.Double click
4.Type "y"...
5.Generate SSDT-HDMI-NVIDIA-PEG0.aml
6.reboot
em,nothing changes.Did I missed something?

Thank you so much in advance for your help.

Same problem, SSDT-HDMI-NVIDIA-PEG0.aml is not seen by Clover and not loading.
How many EFI partitions?
Click to expand...
That's weild. I only have just one efi partitions, and the SSDT-HDMI-NVIDIA-PEG0.aml file exactly exists in clover folder.
Do i need to set "sortedorder" in config.plist to load SSDT-HDMI-NVIDIA-PEG0.aml ?

Never used the property
Since it works for SSDT-PluginType1.aml, add SSDT-HDMI-NVIDIA-PEG0.aml
Click to expand...
sorry for my bluntness， do you mean there is no need ?
besides , how could i load SSDT-HDMI-NVIDIA-PEG0.aml for now?
what is the next step?

you said 'never', i take it as 'don't add SSDT-HDMI-NVIDIA-PEG0.aml to sortedorder '
sorry for my poor english again.
i'll try add SSDT-HDMI-NVIDIA-PEG0.aml in clover.

Edit: after trying, I checked DPCIManager/Misc/boot log.
Code: 
3:640  0:002  Inserting table[1]:SSDT-HDMI-NVIDIA-PEG0.aml from EFI\CLOVER\ACPI\patched ... Success
means it loaded, right? But nothing changed.
new file attached . Thanks again!
