Hi again Toleda.
Still struggling with my HD 530 HDMI. Can't boot with my internal display connected. Disconnected everything works fine with Nvida and two HDMI devices turns up. Optical sound working with both Nvidia and HD 530. Something must be wrong with the injected frambuffer "t2-10.11.4-SKL-1912000-Port_0x6-DP2HDM". You write in your guide that in some cases DSDT edits may be necessary. Could that be the problem for me and in that case how to solve the problem.

Regards
Öbus

IOReg shows the patch, no display attached. Why?
No. ssdt makes dsdt edits, no issue.
Kext patch required
10.12.4/Skylake/framebuffer/0x00 00 12 19 :
Native:
02 04 0A 00 00 04 00 00 87 01 00 00
KextsToPatch/Find:
02 04 0a 00 00 04 00 00 87 01 00 00
KextsToPatch/Replace:
02 04 0a 00 00 08 00 00 87 01 00 00

Differences?

Hack was crashing with two displays thats why I disconnected the internal display before I created the ioreg.

Now after patching both displays work simultaneously but still no HDMI sound from HD 530 display.
No other changes.

New IOreg added and boot log also.
  1. HDMI audio is not working/doesn't show into devices
  2. OS X 10.12.4 (16E195) / Lenovo Y510P, Nvidia optimus 755m/ IG4600
  3. Added config.plist, ioreg, script log, and patched files to an archive.

3 kext patches are not working.
Attach Clover boot log and new IOReg.

Look again, IOReg says HD530 HDMI audio working

Hi again Toleda.

Still no progress. The patch you've recommended plus the original port6 patch isn't working if both displays are connected (crashing). It works in that sense that it boots up for each display separately but if I've use it together with alc1220 not even the optical sound works after installing the alcpatch. The thing is that if I do the GFX02IGPU,HECI2HEMI and HDAS2HDEF patching with CloverConfigurator the HDMI port for my HD530 never turns up. If I patch ONLY GFX02IGPU with CloverConfigurator and the other two directly into my DSDT, both ports shows up, but first after I put the SSDT patch generated by your HDMI patch into my DSDT. In this scenario alcpatch 1220 is not working.

If I do everything the straight way with patching all that needs thru CloverConfigurator according to your note 6 in the guide everything works fine with dual monitor and alc1220 sound but no HDMI port for HD530 shows up..

Could you please take your time and have a further look?
Regards
Öbus
