No HDMI Audio with GTX650 and GA-Z77-DS3H

[fortozs]

I made a big mistake and formatted my OSX drive when setting up dual boot the other night. I have been trying to get HDMI audio working again with no luck. I have followed the guides up to the point of a "working" DSDT (with the nvidia edits and a DTGP method added). Hopefully its right but I am having trouble editing the kexts to the proper device id. My device ID should be 1b 0e 00 00 (from IOReg). I am attaching some relevant files. Can anyone help?

Made more mistakes. Current HDMI audio edits do not use DTGP, wrong guide. See Post #1, Mavericks: HDMI Audio - AppleHDA

Thanks a million! Would you happen to have a link to any patches for this?

How did you miss the link provided in Post #2?

I went ahead and just patched the file manually. Here is my new DSDT file. I still can't find "de 10 ea 0b" using HexEdit. Thanks for the help.

Sorry. My brain is fried. I find the device id in the executable. I was trying the info.plist

Wrong patch, your BIOS is AMI.
Wrong guide, all Nvidia 6xx supported natively.

Trash the guide you are using.

I thought my card was supposed to be supported natively. So how can I undo everything? I already tried the last combo fix to try native support, but I had no luck. Is there another guide for my situation?

Combo Update. For the third time, see post #2.

So should I use this guide (referenced from the guide in post #2):

[Guide]_HD4000-hdmi_audio_(dsdt_or_ssdt)_v2.pdf.zip

The one I was using last time was:

[Guide]_Nvidia-hdmi_audio_v2.pdf.zip

I just want to be sure I have the right one before moving forward this time. Also, am I right to assume that I will be making DSDT files that are loaded with multibeast?
