Perfect guide ... Mr RehabMan.

Thank you, again.

Make sure the AppleHDA you're using is patched from the same version of OS X that you're running.

Sometimes you can mix older AppleHDA with a newer OS X. But it is not recommended.

i enable "HDMI-audio, port 0204, 0x0a260005 0x0a260006" like your #1 post and i see at ioreg my (framebuffer@2) before patching for HDMI-audio, the connector-type for AppleIntelFramebuffer@2 is <00 04 00 00>. After patching, it will change to <00 08 00 00>. when i plug my HDMI cable, my screen just goes black and need to force shutdown.
I don't know what's wrong now.... can u please check my files? thanks

You have a lot of mess in your files... for example different layout-ids are being injected in HDAU vs HDEF.
