Lion HDMI Audio
Part 2a: Lion HDMI Audio DSDT Edits/Discrete Graphics - AMD/Nvidia

The DSDT edits are mandatory for HDMI Audio on your Lion system. Editing a DSDT is not as scary as it looks, however, it must be done exactly as described.

What you will need:
1. IORegistryExplorer - available with Xcode for Lion download from the Mac App Store/Developer Tools/Xcode
2. DSDTSE v1.4.3 - http://www.osx86.es/?p=610
3. dsdt-hdmi_audio-v3.dsl: View attachment DSDT-HDMI_Audio_Edits_v3.dsl
Example edited dsdts with working HDMI audio in Lion are available below:
1. GA-H55N-USB3-F5/HD 5870/10.7.1: View attachment GA-H55N-USB3-F4-HDMI.aml
2. GA-H67N-USB3-F7/HDMI/10.7.2-.3 - PEG0 renamed to PEGP, Audio ID:889: View attachment DSDT-GA-H67N-USB3-B3-F7-EHCI-HDMI-889.aml
3. AS-P8H67I-Deluxe-0606/HDMI/10.7.2-.3 P0P1 renamed to PEGP, Audio ID: 892: View attachment DSDT-AS-P8H67I-Deluxe-B3-0606-HDMI-892.aml

Now, is a good time to back up your system. Preferably, you have a bootable backup. Time Machine is not a good choice for the primary backup. The amount of time needed to enable HDMI audio varies from an hour to as long as you are interested.

This guide applies to Mac OS X 10.7.x only.

6. Working HDMI Audio
HDMI audio is available out of the box for the following graphics card with the above DSDT edits.

a. Sapphire Vapor X HD 5770 1GB
b. Sapphire Vapor X HD 5870 1GB
c. Sapphire Vapor X HD 6850 1GB
d. Sapphire Vapor X HD 6870 1GB
e. EVGA GT 430 1GB

For all other graphics cards, more work is required.

If one of the graphics cards above is installed and the DSDT is edited properly, working HDMI Audio (HDAU) looks like this:

HD6870/10.7.1




GTX 570/10.7.1

I think I start with a clean install and latest MultiBeast. If successful, will post back DSDT with edits for GA-X58A-UD7 Rev 1.0. Need to check GA websight for latest BIOS - may or may not update. Have to think about it.
Will post results probably Sat or Sun, 9/17 or 9/18.

Sweeet - do you need 10.7.0 or 10.7.1 kexts or is it just any Loin kexts have the right AppleHDA ? I take it all of the bin patch stuff still applies to get working onboard too ?

There is one advantage to 10.7.1, HDMI audio works without onboard working. With 10.7, onboard had to work for HDMI audio to work. By the way, both AppleHDA.kexts are version 2.1.1. With on board in Lion, AppleHDA was restructured. The info is the same, simply stored in different places. And yes, patching/dsdt injection are required for Lion onboard.

Slight problem here. DSDT (attached) compiled no errors, GFX0 verify - check.GFX0 verified.png


HDAU verify I get thisHDAU verify.png

So, what did I do wrong? What did I miss?

EDIT: my bad - forgot to change address 00010000 to 00030000 in the PEGP I copied.
HDAU now shows correctly in IOReg.

EDIT2: Reboot and still no output device in system preferences sound. More study is clearly in order.
