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

• Attach all requested files to Post (all posts with files attached will be replied to)

Post #2
Nvidia HDMI Audio/10.13.4, 10.13.5, 10.13.6, 10.14+
10.13.5 Update: 10.13.4 fixes work in 10.13.5. Workaround #2, add MatchOS/10.13.4,10.13.5,10.13.6,10.14.x (no spaces)

The process that enabled all Nvidia HDMI audio codecs has been disabled in 10.13.4 AppleHDAController.kext. Device-ids for natively supported Nvidia graphics cards remain and work.

Supported Nvidia HDMI audio controller device ids (10.13.4 AppleHDAController):

• DE 10 C0 0A
• DE 10 94 0D
• DE 10 E2 0B
• DE 10 E3 0B
• DE 10 E4 0B
• DE 10 E5 0B
• DE 10 EB 0B
• DE 10 E9 0B
• DE 10 EA 0B

• DE 10 0A 0E
• DE 10 0B 0E
• DE 10 1B 0E
• DE 10 1A 0E

Workarounds (select one):

1. Backup 10.13.3/AppleHDA.kext_v280.12 prior to 10.13.4 Update, install with kext installer to 10.13.4. See Post #531, credit jch.
2. Add AppleHDAController patch to config.plist/KernelAndKextPatches/KextsToPatch with Xcode:

I have a new ioregistry that has the correct device id for the r9 290 1002:AAC8
Went back and edited dsdt with your hdmi patch to achieve that maybe you can
see something to change?

Sorry about the post reserved means no posting? I can just message?

 

[toleda]

reserved means no posting?

No, it means I can use Post #2 at a later date

correct device id for the r9 290 1002:AAC8

The device_id is correct, however, it is not recognized by AppleHDA. Find a working AMD HDAU device_id and add a compatible injection to dsdt/HDAU/pci1002,aa??, ex. ssdt_lpcb-9series.zip

This can't be right still get wrong id but compiles by
definition block

Not sure how to get under (HDAU)

Looks good! Doing remotely so can't really test a lot @ the moment. Required an additional clover injection for
The AppleAlc kext to work for the onboard on layout id. Showed all zeros on the alc888b layout id.

Hi there, first time posting and first build. I cant seem to get HDMI audio working with this graphics card, I followed the instructions here to get HD530 HDMI audio working previously but I cant seem to get it working for my new card. Only 1 HDMI port is currently working if that makes any difference and I am on F21 bios. I am also using direct HDMI-HDMI cable. In terminal it says HDMI audio is enabled, not sure where I have gone wrong. Any help would be greatly appreciated. I am on Sierra 10.12.6

cant seem to get HDMI audio working with this graphics card

See Post #1/Note: 10xx/Nvidia web driver ...
or Post #1/VIII. Nvidia GeForce Graphics
macOS is configured correctly for Nvidia HDMI audio

Audio ID: 2 is not correct for you system, use Audio ID: 1, ssdt_hdef-1-100-hdas.zip

Thanks for the quick response toleda,

I had been using SSDT-HDEF-HDAS-1.aml previously but changed it in one of my attempts. I have just changed it back and restarted my computer with HDMI hot plugged at desktop but like before I still have no HDMI audio. Does this mean A DP2HDMI or DVI2HDMI adpater will be the only way for me?
