Can't get HDMI audio from GTX 560 Ti

[Some1CP]

I only needed to install Multibeast's ALC887 audio driver (no dsdt) http://puu.sh/6M4zE.png and a Realtek Network driver after I installed my hackintosh, works flawless.

I noticed that OS X doesn't detect the HDMI out for audio of my Zotac GTX 560 Ti, and I tried to follow this guide http://www.tonymacx86.com/hdmi-audio/84936-easy-guide-ml-hdmi-audio-hd4000-7-series-mb-41.html

First, I removed HDAEnabler1.kext from S/L/E, installed the DSDT version of the ALC887 audio codec and applied the "ib2-hdmi_audio_ami_efi_hd4000-1.txt" patch to a DSDT I got from my own system using MaciASL since my system doesn't need or have a DSDT installed.

After rebooting, I noticed that the HDMI still wasn't detected, but a new duplicated Audio output showed up on system preferences http://puu.sh/6M4WK.png , and "Intel HD Audio" on System Information http://puu.sh/6M4Z9.png

I'm using an Asus P8B75-V with a Core i7 3770 and nVidia GTX 560 Ti.

Here's the patched DSDT: http://puu.sh/6M58J.aml
IORegistry before patching: http://puu.sh/6M5c5.ioreg
IORegistry after patching: http://puu.sh/6M5nn.ioreg

Help appreciated.

So I just need to HEX edit the AppleHDAController kext? No need to use your patches? Thanks in advance.

I've replaced the HEX values on the patched AppleHDAController binary and it works great now, many thanks.

Same.

this sollution doesn't work on yosemite. i removed hdaenabler1.kext from s/l/e, i hex edited applehda/applehdacontroller and replaced the values as described, and now i have no audio devices.

 

[toleda]

have no audio devices.

Bad edit or incorrect install.

 

[pyraylos]

i managed to fix the 'no audio devices' using dsdt file. is there a way to enable hdmi audio on my gtx560ti by using a patch for dsdt and not by hex editing applehdacontroller?
