    ML: UEFI HDMI audio, no dsdt edits



    HD4000 HDMI Audio, no dsdt edits required
    Ivy Bridge/7 Series/Socket 1155/UEFI - HD4000/AMD/Nvidia HDMI Audio

    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)

    1. AMI UEFI BIOS - native dsdt, no dsdt/HDMI audio edits (see Note 1)
    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)

    Download
    See link above.
    Location.aml - dsdt.aml/ssdt.aml installation folder

    1. Chameleon/Chimera - Extra/
    2. Clover - EFI/Clover/ACPI/Patched/

    Installation

    1. Copy Downloads/ssdt-audio_uefi_hdmi_v3/SSDT-1.aml to Location.aml
      1. If Location.aml/SSDT.aml is present, install Downloads/audio_ssdt-uefi_hdmi_v3/SSDT-1.aml as Location.aml/SSDT-1.aml
      2. If no Location.aml/SSDT.aml, rename Downloads/audio_ssdt-uefi_hdmi_v3/SSDT-1.aml to SSDT.aml and install as Location.aml/SSDT.aml
      3. The 1st SSDT is SSDT, 2nd is SSDT-1, 3rd is SSDT-2, etc.; no gaps

    2. Enable SSDT
      1. Chimera or Chameleon - Extra/org.chameleon.Boot.plist
        1. Code:
          <key>DropSSDT</key>
          <string>Yes</string>

      2. Clover_v2000+ - EFI/CLOVER/config.plist/ACPI/SSDT
        1. Code:
          <key>DropOem</key>
          <true/>

    3. Rebuild kernel cache - see Tools: 4
    4. Restart
    5. Verify HDMI audio

    Native HDMI Audio Graphics

    1. HD4000 (framebuffer editing may be required)
      1. HDMI display on port 0x7, native, typically, Gigabyte and Asus motherboards
      2. HDMI display on port 0x6, framebuffer edit required (see guide below), typically, Intel, MSI, and Zotac motherboards
      3. DP audio supported on port 0x5 and port 0x6

    2. Nvidia 4xx/5xx/6xx7xx
      1. ​Not supported natively: GTS 450, GTX 550ti, and GTX560ti
      2. All Nvidia graphic card connectors support HDMI audio (DVI2HDMI, DP2HDMI)
      3. DP audio supported

    3. AMD HD5xxx/HD6xxx (framebuffer injection and editing may be required)
      1. ​Framebuffers, see ATI/AMD 5xxx & 6xxx Graphics Cards Framebuffer Personalities
      2. Framebuffer edits, Lion HDMI Audio - Part 3a: Kext Edits - AMD
      3. DP audio supported

    4. Supported Configurations (ML UEFI HDMI Audio SSDT)
      1. ​HD4000 only
      2. Nvidia only
      3. AMD only
      4. HD4000 and Nvidia
      5. HD4000 and AMD

    Troubleshooting

    1. Verify HDMI device connected
      1. System Information/Graphics/Display/HDMI device name/Television/Yes

    2. Run IOJones/Verify Devices (PEGP, GFX0 and HDEF)
      1. Device (GFX0) may not be present if HD4000 Graphics is not enabled
      2. Device (PEGP) may not be present if no discrete graphics

    Problem Reporting

    1. Motherboard/BIOS version/processor/graphics/OS and version
    2. Iinstalled SSDT
    3. Extra/org.chameleon.Boot.plist or Clover/config.plist/
    4. IOJones or IOReg

    Notes

    1. Do do not use this method if you already have HDMI audio
    2. Any post requesting help on anything other than an UEFI/Ivy Bridge/HD4000 processor/7 Series motherboard will be deleted

    ML: UEFI HDMI audio, no dsdt edits


    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?

    ML: UEFI HDMI audio, no dsdt edits


    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 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

    Missed the very first requirement:

    1. AMI UEFI BIOS (native dsdt, no dsdt/HDMI audio edits)
