Audio - HDMI Audio AppleHDA [Guide]

The compile is giving me the warning

trying to activate HDMI audio and while reading the Post 1, I still have some newbies question.

The point is made many times, HD3000 HDMI audio only works with Audio ID: 3. Patched AppleHDA.kext supports Audio ID: 1, 2 or 3.
Try:
MultiBeast - Select: Drivers > Audio > Realtek ALCxxx > √ ALC889
Plus √ Optional HD 3000/HD 4000 HDMI Audio

Attach IOReg.

Ok, I did that and I have patched the one that is "Enables LC" and put the new DSDT in the "Extra" folder. I have ran the AppleHDA command and the IntelFrameBuffer command, I used "B" for HD4600 and it is not working. I also have ran Multibeast and selected and built with the "Optional EFI Installed Bootloader Support". Do I have to add a key or string to the "org.chameleon.Boot.plist"?

Ignored previous request, not helpful.
Why?
Why?
Are you using Clover? If no, do not use that option.
No.

IOReg shows you did not install as noted; Audio ID is not correct. Try again.

Ok so retried to install ALC889 and tick Optional HD 3000/HD 4000 HDMI Audio option with same result: no sound and no HDMI Output line in Prefs.

Have attached more files. I am using MB 7.2.0 and Yosemite 10.10.3.

Are you checking HDEF@1B in IOReg ?

 

[toleda]

no sound and no HDMI Output line in Prefs.

Did not mention the installed dsdt.
Fix (choose one):
1. How to Add or Edit dsdt/HDEF v2
2. Edit dsdt/HDEF code to:

                            "layout-id", 
                            Buffer (0x04)
                            {
                                 0x03 0x00, 0x00, 0x00
                            },

Reply withe edited dsdt and IOReg.

In the future, no need for:
MultiBeast: Drivers > Audio > Realtek ALCxxx > Optional HD 3000/HD 4000 HDMI Audio

Not HDMI audio, off topic.
