Audio - HDMI Audio AppleHDA [Guide]

[rcolem87]

dsdt edts, yes (see Post #1). Clover patching, no.
The HDMI audio guides enable all integrated and discrete graphics combinations.

Even a board that was supposedly suppose to work dsdt free? My Gigabyte GA‑Z97N‑WIFI Board, with EVGA GeForce 750 Ti GPU would have hdmi audio out (most importantly)? For the past month I was sure there was no way to get it.

There is no such thing as dsdt free; all Intel systems have a dsdt. The native dsdt enables many desired capabilities and does not enable others such as OS X HDMI audio. In summary, no OS X HDMI audio with non native hardware. The Post #1 guides provide instructions/tools/files to enable OS X HDMI audio on most non native hardware.

Toleda - as requested, I have attached the "problem reporting files" and could use guidance Step 1 and on really. Trying to determine what AppleHDA.kext I need, which azul frame buffer kext I need (a-g), then dsdt vs ssdt. I do have onboard optical audio working excellently.

Thank you.

Why did you select HD3000/HD4000 HDMI audio with HD4600?
Install MultiBeast/ALC892 again, no options.
Framebuffers: click the link in the guide. It says how to find the port the display is connected to.

Problem: 10.10.2/MultiBeast 7.2/ALC892 on 10.10.1 does not work.
Fixes (select one):
1. Install MultiBeast 7.1.1/ALC892 on 10.10.1
2. Update to 10.10.2, Install MultiBeast 7.2/ALC892

Port 0x7 is the only required patch for the connected display
Hot plugging HDMI results in an Intel driver crash, not recommended.

Roger that.
And I got another strange problem.

When I patched DSDT without Kext Patch, I followed a guide to find out which port-number did HDMI use.
I only tested DVI and HDMI

When I plug DVI cable, the display shows in AppleIntelFrameBuffer@1, and port-number is 0x6.
Then plug HDMI cable, the display shows in AppleIntelFrameBuffer@2, but port-number is 0x0 ?

Is that normal?

Thank you sir. Baffled me for a few hours.

Yes, non native hardware anomaly. Connect a display and it shows as Port 0x7.

I plug HDMI as display to TV, it still shows 0x0, but if I use Kext patch it shows 0x7.
