Lenovo Yoga 2 13" Yosemite

[Glorianx]

Hi i've installed Yosemite 10.10.3 on my Lenovo Yoga 2 13" with i3 4030U, Intel HD4400, display FHD Touch.
everything works perfectly, graphics acceleration is ok, maximum resolution, brightness control, audio ALC235 with AppleHDA patched. The only thing that I can not run is the HDMI audio. No HDMI output device is present.
I enclose all the configuration files and patches that I am currently using.
I apologize for English because I'm Italian and Use google translator.
Thanks so much for all the work you do

HDMI-audio on Haswell has several requirements:
- the device at address 0x00030000, usually called B0D3, must be renamed to HDAU
- the resulting HDAU device must be recognized by AppleHDAController (config.plist patches required if not natively recognized... or you can use FakePCIID_Intel_HDMI_Audio.kext)
- your framebuffer must be patched for HDMI-audio (there are patches in my default config.plist (disabled) files: https://github.com/RehabMan/OS-X-Clover-Laptop-Config). It is trial/error to determine which port your HDMI is connected (actually, they are positional and you can tell by looking at ioreg).
- patched AppleHDA is required (sometimes VoodooHDA works, but my experience has been not good)
- you have to inject "hda-gfx"="onboard-1" for IGPU/HDEF/HDAU objects. This is usually done with DSDT/SSDT edits (_DSM methods)

I renamed B0D3 toHDAU in SSDT and I copied Fake CIID Intel HDMI Audio.kext in System / Library / Extensions. But now I do not know where to find the output port of HDMI and where to insert it. Excuse me are not very practical.
Thanks for the help

It is trial/error. If you plug in an HDMI monitor you can see if you patched the correct entry.

Thanks a lot RehabMan, now works HDMI audio. I could not have done it without your help. Now works almost everything, you know show me how to remap the keyboard function keys?

You are the best

Hello RehabMan
I would like to remap the keys for brightness on my Lenovo Yoga 2 13.
F11 Brightness less
F12 Brightness More
The two keys do not generate PS2 scancode
I installed ACPIDebub.kext and I patched DSDT
By System Log I note that F11=EC _Q11, F12=EC _Q12
How can I patch the DSDT?
I must also change voodoops2keyboard plist?
