AppleHDA HDMI Audio [Guide]

[taihuynh]

Hello Toleda,

Followed your instruction, I'm trying to enable NVIDIA GTX 750ti audio over HDMI but no luck. IORegistry shows device ID (or something) instead of HDAU as per you screenshot in first post.

Could you please help to look into the attached files and guide for any that I can do next.

Much appreciated.

Hello Toleda,

Never mind. It's fixed already.

1. Corrected Layout-ID on my DSDT.
2. Fixed onboard audio first with Clover-Native AppleHDA.kext solution.
3. Used Audio-HDMI command to install the suggested SSDT.
4. Corrected PEGP device and added HDAU device on my DSDT by SSDT in step#3.
5. Removed SSDT from Clover patched folder.
6. Added Clover KestsToPatch entry:

• Name kext: com.apple.driver.AppleHDAController
• Find DE100B0E
• Replace DE10BC0F

Anyway, thanks for your hard work.

Hey Toleda,

There's nothing attached. Confirmed bootable USB drive.

SSDT installed

Progress, 2 experiments:
1. Install attached dsdt to CLOVER/ACPI/patched/
2. Remove CLOVER/ACPI/patched/DSDT.aml and SSDT-HDMI-AMD-PC02.aml and install attached ssdt to CLOVER/ACPI/patched/

Reply with IOReg and boot log for each experiment.

Hey Toleda,

Thanks for all your help.

DSDT failed to boot. Here are files for SSDT-HDMI-AMD-PCO2-1.aml.

One note, I still have ssdt_hdmi-amd_fb_inj-PEG0.dsl in my ACPI - patched folder. Should it be there, or must I remove it as well?
