Demystifying HDMI Audio Part 3a: Kext Edits for AMD 5xxx

Enabling HDMI audio via AppleHDA in Mac OS X 10.6.x is comprised of four guides:
Snow Leopard HDMI Audio - Part 1: Requirements
Snow Leopard HDMI Audio - Part 2: DSDT Edits
Snow Leopard HDMI Audio - Part 3a: Kext Edits for AMD 5xxx
Snow Leopard HDMI Audio - Part 3b: Kext Edits for NVIDIA 4xx

Please note: This guide applies to Mac OS X 10.6.5, 10.6.6 and 10.6.7 only. The Early 2011 MacBookPro 10.6.7 release, Early 2011 iMac 10.6.7 release and Mac OS X 10.7 are not considered.

Even with a successfully configured DSDT, more work is required. Specifically, your system must be enabled for the specific graphics card you have installed. Typically, this means editing particular software components in your system for compatibility with your graphics card. There is a specific method for Nvidia GeForce GT4XX graphics cards and a different method for AMD Radeon HD 5XXX graphics cards.

What you will need:
DSDTSE v1.4.3 - http://www.osx86.es/?p=610
IORegistryExplorer - Mac OS X Retail Install Disc v10.6 or v10.6.3 (Optional Installs/Xcode)
HexEdit v220 - http://hexedit.sourceforge.net/
dsdt-hdmi_audio-v2.dsl

radeon_bios_decode - http://www.insanelymac.com/forum/index.php? showtopic=249642
vbios - see HDMI Audio Kext Verification

Additional Audio Kext editing details are included in HDMI Audio Kext Verification

HDMI_Audio_Kext_Verification.pdf

Depending on how your graphics card is enabled, additional edits of your DSDT may be required. The edits are defined as GraphicsEnabler=Yes or Graphics Enabler=No.

Two components of AppleHDA are relevant to enabling HDMI audio. They are 1. AppleHDA binary and 2. AppleHDAController binary. For AMD graphics cards, the AtiFramebuffer binary is also important. HexEdit is the tool used to edit each of the binaries. Additional information describing AppleHDA and HexEdit are available in HDMI Audio Kext Verification.

Some information for your reference.
My card was MSI HD5670 with HDMI device id "60 aa", codec is "aa 01",
However, I still need to patch ATIFramebuffer and AppleHDA to make HDMI+Audio work.

No AppleHDA patch is required. Try your card with the HDMI audio DSDT edits. Most likely, you have to edit ATIFramebuffer. You have to get a copy of the VBIOS for your card and perform the edits as described. Good luck

Hi toleda
I have my DSDT edit same with yours, and also have VBIOS for my HD5670.
The problem is not HDMI/DisplayPort audio output, it's on-board audio output.
If I did not patch AppleHDA, there will have problem with ALC889 outputs.
I will got sound assertion error and ALC889 can not work.
I think your on board audio was ALC892, maybe it's the different from mine.

You're right. For HDMI audio, with you're graphics card, no AppleHDA edit is required. For on board audio (off topic), you have to patch AppleHDA for your motherboard. There are many guides for enabling on board audio. It is good to hear you have both HDMI and on board audio working. Hopefully, many others will have the same success.

Hey Toleda, I am currently on 10.6.6 with AppleHDA 1.9.9 and modified DSDT from a friend. If I were to update to 10.6.8, will I still have HDMI audio?

I'd suggest going only to 10.6.7. I have not gotten HDMI audio to work on 10.6.8, yet.

How do you get the volume control working?
Because I got this working on my 4670 (YEAH!) but I don't have control over the volume....

What device is the HDMI cable plugged into (TV, receiver, etc.)? Use that device for volume control.

Re: Demystifying HDMI Audio Part 3a: Kext Edits for AMD 5xxx

The HDMI port is connected to my monitor, and I have my speakers connected to that monitor. I can adjust the sound on my speakers, however when I use my headphone, connected to my speakers, I cannot change the volume using the speakers' volume control. Which is why I need the volume control on the hackintosh to work.
