[Easy Guide] ML: UEFI HDMI Audio

[toleda]

I have to say I am pretty much stunned by this work.

Thanks.
The ssdt complier problem is just that, different compilers do different things; the binary is valid. The interoperability credit goes to Nvidia, NVCAP instead of framebuffers and wildcard device-id verification.

GT 210 HDMI audio is not supported in OS X.

Please help guys!

Specs:

ASUS P8PO67 DELUXE REV 3 BIOS 2103
Intel Core i7 2600-k
nVidia GT430

Install osX with User DSDT, ALC889, and AppleIntelCPUPowerManagement.

I followed the instructions here with the uefi1 patch, but got an error. After reboot I still have no audio. Can someone take a look and see what I did wrong? Thanks!!

Wrong guide, you do not have UEFI. See HD3000/6 Series MB dsdt edits - Desktop, Mountain Lion HDMI Audio - AMI DSDT
As well, your graphics card is in the wrong slot.

Thanks for the help! Which slot should it be in?

The dsdt edits appear correct. The IOReg shows no HDMI audio and the dsdt is not installed.

This step was not done:
22. MaciASL/File/Save As... /ACPI Machine Language Binary/Extra/dsdt.aml (add extension)

Reply with an IOReg with the dsdt installed.

 

[JunkLee]

Thanks for your quick reply!

I repeated the steps and installed the DSDT in /Extra folder. But same things

Attached IOReg with the dsdt.aml installed
