Help with HD4000 Graphics and HDMI Audio-GA-Z77X-UP5TH and MSI GeFORCE GTX 680

Mountain Lion Version 10.8.3

What I want to do...

Im gonna be buying a couple extra TV's soon(totaling 3)and I want to be able to hook them all up via HDMI. One monitor from the HDMI on the MOBO and the other 2 monitors via HDMI and, thunderbolt to HDMI from my GPU and also get HDMI audio on the TV's from each.

My Predicament... :cry:

So I've put everything together and done my install. I have windows running on one SSD with an HDD as storage and Mac running on the other SSD with the other HDD as storage. But on the Mac side I only have Video from the inputs on my GPU. I cannot get the onboard HD4000 video working and I also cant get audio when I have the HDMI on the GPU plugged in. I only get audio from the front panel audio port and the green audio port on the back. Everything else regarding the install works fine (I.E. Wifi,Sleep/Wake,USB 3.0 ports,bluetooth dongle,and I can boot up perfectly without having to use any boot codes).

I wanted to know if it is even possible to do what Im asking, which is run multiple displays off both the MOBO graphics and GPU and also get audio from each at the same time and if so how do I go about accomplishing this task?

I am not extremely versed in all that is hackintosh so please be gentle

and thanks so much in advance for your help!

No thunderbolt ports on the 680; 680 supports 4 displays, all can have HDMI audio. Thunderbolt uses HD4000 graphics.
No OS X HDMI audio without a HDMI audio edited dsdt.

Steps:
1. Remove 680 and get HD4000 video working
2. Install 680 and get both graphics systems working, see Mountain Lion: HD3000/HD4000 with AMD or Nvidia, Working Together.
3. Implement power management, see ML: Native Ivy Bridge CPU and GPU Power Management
4. Enable HDMI audio, see [Easy Guide] ML: HDMI Audio/HD4000/7 Series MB

For any problem, attach the dsdt and a copy of IOReg. [Guide] How to Make a Copy of IOReg.

Sorry I meant the display port on the GTX 680.
So should I just take out the video card and redo the ML 10.8.3 install while connected to the MOBO graphics? What BIOS settings do I need when doing this?
Also since my MOBO doesnt have a DSDT how would I go about creating one? (Never done it before)

Suggest you read the guides before you start.

Ok so I got the HD4000 graphics working.

Look about right. Figured a round about way to get it done and turns out I was already half way there. Glad I didnt have to take out my graphics card!

But in regards to the HDMI Audio I think Im gonna have to hold off on that. Im a little over my head when it comes to DSDT Edits. This being my first hackintosh build and all.
And about the power management, what does that do exactly?

Question...as a work around for the HDMI Audio would the Optical S/PDIF out work on my MOBO from anyones experience? Wanted to find out before buying the cable.

Search Intel SpeedStep. SPDIF/Optical works on your motherboard in OS X.

Hey Toleda thanks so much for all your help so far Ive got another question though. Regarding DSDT edits for HDMI audio, do I need to have all the displays I want HDMI audio on hooked up when doing the edit or not?

One HDMI audio capable device must be attached during testing, otherwise, no way to know it is working.
