[Easy Guide] ML: HDMI Audio/HD4000/7 Series MB

Thanks Todela, but by reading your guides, I realize that I would not be able to patched my own AppleHDA. This is out of my league. Can I change something in my DSDT so one of my port would be seen as the Black/Line Output on Layout-id 3?

No.

Alright, thanks for your time

DSDT edits are correct. Problem is on the motherboard. The physical HDMI connector is assigned to a DP connector (port 0x6) in the framebuffer rather the the HDMI connector (port 0x7). An edit to the framebuffer is required to change the DP connector to a HDMI connector.

Just got around to trying this and it worked! Thank you so much - you're a genius!

First of all, after lots of messing around everything seems to be working with my build. Huge thanks to toleda and everybody else in this thread for the contribution and instructions.

However, I can't seem to figure out how to map the Framebuffer properly.

The Zotac Z77ITX has:

2 x HDMI Port
1 x Mini DP Port

Am I supposed to change the connector to 05 or 07? I'm really confused. How should I edit the file to reflect the changes?

Thanks! It's fully working now. The only troublesome part is that I need to prepare to KEXT version in order to switch the HDMI audio out if I were to use the connector without assigned frame buffer
