Thanks fearteach. How to patch hda-gfx to hdef?? I tired to apply intel 4000 low resolution patch but it only apply to igpu/_dsm

I made mistake. should it be rename to match like at origin ssdt order?
first thing is to not rename your ssdts, as that gets confusing, everything you need is in the guide here:

once you have a bootable system with ssdts in place and a sorted order, then you should work on your HDMI audio

well done :) you won't be able to control the hdmi volume via your hack, only through the tv

Hi,Rehabman.
I have some trouble in HDMI output with HD530.When I plug in my external display, no new "display0" appear under "AppleIntelFramebuffer@1" and "AppleIntelFramebuffer@2".So I add the 4-display patch:
Code:
Name:AppleIntelSKLGraphicsFramebuffer
Find:01030303 00002002
Replace:01030403 00002002
And "AppleIntelFramebuffer@3" appear, but its port-number is 0x0 instead of 0x7. How can I fix it?

Code:
