HDMI Audio AppleHDA [Guides]_v4.0
#HDMI Audio AppleHDA [Guides]

OS X Intel HD Graphics/AMD/Nvidia HDMI audio

Clover HDMI audio enables HDMI, DP and DVI audio with patched or native OS X AppleHDA.kext. HDMI audio ACPI edits are enabled with dsdt edits, edited ssdts or Clover injection/dsdt patching. Clover provides audio and graphic binary patching while preserving native kext installation. Supports Intel HD Graphics and/or AMD or Nvidia HDMI audio.

cloverHDMI detects and installs the correct ssdt(s) and patches the Intel framebuffer for the connected display(s) enabling OS X HDMI audio.

Clover HDMI audio for NVIDIA & AMD cards. Easy way.

ok1ok1

Updated 07/3/2018. This solution works in High Sierra 10.13.6 as well as several previous versions of MacOS. I didn’t create the tools I only figured out how to use them. Credit for the kext goes to andrejkw at macrumors. Your mileage may vary but this is the easiest solution I’ve found. I’ve used it for years & its worked for many others. Definitely worth a try.

1. Download package located here https://www.dropbox.com/s/8hay1m0rec93vvo/HDMIAudio-1.0.dmg?dl=1
2. Mount HDMIAudio-1.0 disk image
3. Mount your EFI partition. You may need to use Clover Configurator or similar tool to do this.
3. Copy HDMIAudio.kext from the HDMIAudio disk image to EFI/Clover/Kexts/Other
4. Reboot. Clover may hang on the initial boot attempt, if so a restart of the computer should have you up and running.

There you have it, a simple file copy.
After the reboot I had working HDMI Audio.
*If you don’t see any audio devices after reboot. Download and run AudioCloverALC command by toleda
https://github.com/toleda/audio_CloverALC/raw/master/audio_cloverALC-130.command.zip
This may help to finish off the install.

If you’re confused, there is a quick rundown in this video. *VIDEO IS OLD. COPY KEXT TO «OTHER» FOLDER!
*Don’t forget to select the proper output! System Preferences/Sound/output or hold the Option key while clicking volume icon.

So now you have HDMI audio, but what about volume control? OSX doesn’t support volume control of HDMI devices natively. Use one of the utilities below to enable it.

      Notes/Nvidia:

      • Nvidia 10xx/web driver; no HDMI audio on HDMI port after boot. Try all DP connectors and/or DPDVI2HDMI or DVI2HDMI adapters for HDMI audio (4K@60 HDMI requires active DP adapter). Two displays, see Post #235, credit:
        Pintglass
      • macOS only supports video on one HDMI port on a Nvidia graphics card with more than one HDMI port. Use DP2HDMI or DVI2HDMI adapters for multiple HDMI displays (4K@60 HDMI requires active DP adapter).

      First time, see I. Before You Install HDMI Audio, below

      Installation: see II. AppleHDA HDMI Audio Methods, below

      1. cloverHDMI: detects and installs the correct Intel, and/or, AMD or Nvidia ssdt(s) and patches the Intel framebuffer for the connected display(s) enabling persistent macOS HDMI audio.
      2. Intel/FakePCIID: 2 kexts that provide an alternate PCI ID to a given IOPCIDevice combined with a device id injector, required framebuffer patches must be pasted to config.plist; best laptop/NUC support
      3. AMD/Nvidia/Intel/WhateverGreen: 1 kext that enables AMD HDMI audio with the default framebuffer, configurable with boot arguments
      4. Unsupported Methods: HDMIAudio.kext, Voodoo, etc.

      Support: see IV. Problem Reporting, below
