OS X HDMI audio for UEFI/Ivy Bridge systems with the native dsdt. One step, install the HDMI audio enabling SSDT to Extra and restart to HDMI audio. More good news, the ML HDMI Audio SSDT survives OS X and BIOS updates. Ideal for systems with no onboard audio requirements (i.e., HTPCs, BRIX, NUC), uses native AppleHDA.kext.

UEFI HDMI Audio ssdt - Desktop
audio_hdmi_uefi/ssdt_7series at master · toleda/audio_hdmi_uefi

Requirements (this version, UEFI HDMI Audio SSDT)

  2. Ivy Bridge/HD4000 processors/7 Series motherboards only (see Note 2)
  3. HD4000 and native OS X HDMI audio graphics support including Nvidia 4xx, 5xx, 6xx and some AMD
  4. OS X 10.8.4 and newer.
Before You Start

  1. OS X does not provide HDMI audio controls (No volume, no mute, no balance, etc.)
  2. The connected HDMI device (TV, receiver, etc.) provides any and all audio controls
  3. Remove S/L/E/HDAEnabler1.kext or S/L/E/HDAEnabler2.kext (if present)
  4. Remove any property-type injection (Extra/org.chameleon.Boot.plist)

I did what you said, however I do not get HDMI audio. Firstly I am not sure about one thing - do I need an unedited DSDT in extra folder or can I just remove it since I only use it for HDMI audio edits.

I am AsRock z77 Pro4-M with modified bios v1.60 with i5 3570k as the processor. My graphics card is Sapphire Radeon HD 6870 which I needed to edit the kext to get working. I'm using Mountain Lion 10.8.4

I have attached the IOJones files however I do not understand when you say "Copy of installed SSDT". Do you mean, the ssdt file I downloaded from this post or my current ssdt so the system definition?

Worked on my UD5H with a 650ti. The directions seem a little complicated, but it really isn't. All I did was unzip the file, rename SSDT-1.aml to SSDT.aml and drop it in my Extras folder located at the root of my boot drive. Easy, thanks so much for making HDMI audio so easy. As a note, HDMI audio wont show up under system preferences unless, there is an HDMI device connected.

IOJones is incomplete and not helpful. Why are you messing with a system that already works?

There should not be 2 Intel High Definition Audio entries in your screenshot. Looks like you did not follow the complicated instructions. Specifically, Remove S/L/E/HDAEnabler1.kext or S/L/E/HDAEnabler2.kext (if present)

Sorry about the iojones. Im just curios and wanted to try it :D Im not a huge fan of messing around with DSDT's so I thought if this works, it will make future installations a bit simpler. I've attached another iojones file hopefully this time I did it correctly

Hi toleda,

I tried the SSDT but there is no HDMI audio on HD4000. With my own patched DSDT there is HDMI audio so I suppose the framebuffer patch for my MSI board is correct. I want get rid of my DSDT because the operation regions always change after bios settings and I have to change the dsdt every time.

If I boot stock (without my DSDT) the HDEF DSM from SSDT injects, I have audio with ID 3, but no HDMI audio. Maybe the path in my ACPI tree is different for GFX0 and the SSDT need some changes??
