Audio - HDMI Audio AppleHDA [Guide]

[tyk5555]

Hi toleda, I followed post#1 instructions, but after run audio_cloverHDMI-120_v1.0d.command and reboot, my internal screen glitch and external monitor no signal, so I cannot log in to the macOS.

I try to remove Device (GFX0) in SSDT-HDMI-NVIDIA-PEG0.aml, internal screen and external screen works fine and I can see HDAU in IORegistryExplorer but still no HDMI/DisplayPort audio. Can you help me about this issue?

Thank you very much.

is there something we must remove first before running the .command?

No.

That is why there is no HDMI audio. Editing ACPI files is a bad idea. GFX0 is not the problem.
Are the attached dsdt and ssdts in EFI/CLOVER/ACPI/patched? if yes, why?
Attach SSDT-HDMI-NVIDIA-PEG0.aml

Thanks for your reply

Yes, they are in EFI/CLOVER/ACPI/patched.

SSDT1 ~ SSDT5 are original files extracted from CLOVER F4 key, I just copy them into patched directory without any modification.
SSDT.aml is generated by https://github.com/Piker-Alpha/ssdtPRGen.sh
I only modified DSDT.aml, fix compile error, applied DTGP, Clean Compile, Skylake LPC and USB patches from RehabMan and you.

If I remove all DSDT and SSDT files from patched directory and only use SSDT-HDMI-NVIDIA-PEG0.aml, the glitch issue still exists.

Here is SSDT-HDMI-NVIDIA-PEG0.aml generated by audio_cloverHDMI-120_v1.0d.command.

Hi Toleda

Was using intel HD530 with working DP audio to my monitor.

Installed a 1050Ti, DP to same monitor. Latest web driver, lilu.kext+NvidiaGraphicsFixup.kext to avoid black screen.

All works great except DP sound.

10.12.4 - i7 - Gigabyte Z170X-UD5
Used the audio_cloverHDMI-120.command.zip guide

Here are all the files (I hope!)

No a good idea. Leave SSDT.aml (pm). Add lpc ssdt and usb ssdt. Remove DSDT.sml and SSDT1 - 5.aml

The only problem to solve as why your system is haveing a problem with the Nvidia ssdt. Do you have another macOS system to screen share with the lap[top?

I only have Linux or Windows on other machines, could I use third party remote desktop software?

Searched and seems VNC would work.
So I should collect the ioreg and boot log?

Something else was first and it ensures all other attempts will fail.
