My mistake, Post #1855 updated

with these changes the hdmi monitor resolution was wrong, the ldvs display was black and the hdmi audio not work.
attached new files and edited kext. Maybe something goes wrong due to the patched AppleHDA.kext?

The edit is correct. Different problem; HD4000/Framebuffer/ig-platform-id/0x01660003 did not load; not obvious, why.
Instead, install native AppleIntelFramebufferCapri.kext and rebuild kernel cache.
config.plist/capri edit is correct.
Restart, reply with new files.

11/2/16 attached IOReg/HDEF/hda-gfx present.
Clover kext patch does not effect ACPI tables.
Rebuild kernel cache and restart.

I run

sudo touch /System/Library/Extensions && sudo kextcache -u /
and this is the output

changed config.plist/Devices/UseIntelHDMI
from: NO
to: YES

now HDMI audio works!!!

But due to my thirst for knowledge i have to know if it works for kext patch or dsdt edit. So I disable the kext patch inside config.plist and then I'll tell you if everything works.

Edited: both are needed. I attach the whole configuration. THX
