Snow Leopard HDMI Audio - Part 3b: Kext Edits for NVIDIA 4xx

Demystifying HDMI Audio Part 3b: Kext Edits for NVIDIA 4xx

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

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

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. HexEdit is the tool used to edit each of the binaries.* Additional information describing AppleHDA and HexEdit are available in HDMI Audio Kext Verification.

Re: Demystifying HDMI Audio Part 3b: Kext Edits for NVIDIA 4xx

Hi everybody!
First of all i want to thank toleda for this excelent guide. I nearly got it working but stuck with the last part - kext editing.

My hardware:

MB: Asus P5E (Ad1889b codec)
Video: Zotac GTX 470

My Software:

Mac OS X 10.6.7 (installed 10.6.3 vanilla with chameleon 2 rc5 and updated from software update)
AppleHDA v 1.9.9f12 (extracted from 10.6.7 combo update)
NVidia native drivers
DSDT fixes for motherboard from this thread: http://www.insanelymac.com/forum/index. ... pic=199816

My DeviceID for HDAU@0,1 from IORef is: e5 0b
My IOHDACodecVendorID for IOGDACodecDevice@0,1,0 is: 10 de 00 10

AppleHDAController binary pathed: OK

The problem is: I can't find 14 00 de 10 code in AppleHDA binary. However i found 0a 00 de 10 and tryed to replace it with 10 00 de 10

After that, i have HDMI audio (and built in audio in System Profiler, screenshot attached). But HDMI audio still doesn't appear in Audio-MIDI setup, and doesn't work.

Any help would be much appreciated!

My DSDT.aml video section:

Code:

Re: Demystifying HDMI Audio Part 3b: Kext Edits for NVIDIA 4xx

Hi everybody!
First of all i want to thank toleda for this excelent guide. I nearly got it working but stuck with the last part - kext editing.

....

After that, i have HDMI audio (and built in audio in System Profiler, screenshot attached). But HDMI audio still doesn't appear in Audio-MIDI setup, and doesn't work.

Any help would be much appreciated!

Thanks for your feedback. 14 00 de 10 is not in AppleHDA binary v1.9.9; my mistake. You chose a good alternative. In IOReg, you will see NVDA,Display-A@0 and NVDA,Display-B@1. Underneath one or the other will be display0. Select the NVDA that has display0 attached. Please verify audio-codec-index, av-signal-type and connector-type and their value. You can also pm a copy of your IOReg.

Thanks for fast reply!

It seems to be a little different in my case.
Attaching a screenshot of IOReg GFX0. Also must say that my monitor is plugged into second DVI port.

Sent you pm with IOReg dump.

Are you saying you have a DVI monitor plugged into the DVI port? Do you have a TV (or other HDMI device) plugged in the HDMI port as well?

Re: Demystifying HDMI Audio Part 3b: Kext Edits for NVIDIA 4xx

Yes, exactly. Monitor is plugged in second DVI and TV is plugged into HDMI. First DVI is empty.
-- EDIT --
I just wanted to point that the second DVI port is used for monitor if it makes any difference.
Also i got this in kernel log - only one line:

Code:

Jun 23 04:38:58 localhost kernel[0]: Sound assertion "0 != createAudioEngines ( fPathMap_aDriverInstance )" failed in "/SourceCache/AppleHDA/AppleHDA-199.4.12/AppleHDA/AppleHDADriver.cpp" at line 202 goto Exit

There is some another line wich i can see during boot, but somewhy it doesn't get logged.. It's similar error telling something about pciVendorProduct ID unknown.. I'll try to shoot it and upload
-- EDIT2 --
Second error photo attached

-- EDIT3 --
Ok, got it from dmesg

Code:

Sound assertion "0 == pciVendorProductID" failed in "/SourceCache/AppleHDA/AppleHDA-199.4.12/AppleHDAController/AppleHDAController.cpp" at line 3345 goto Exit

I need to see About This Mac/System Profiler/Graphics/Displays. Thanks.
