Problems related to HDMI

[cagalindo]

Hey guys, what's up.
So, I'm trying to make my HDMI/HDMI Audio work.. but i'm facing problems with both.

Hdmi: When I connect, most of the times, mirror display does not work. I get video on my TV, but my laptop keeps in a black screen, even though I disconnect the cable, I still have black screen and can't turn the laptop display on (only restarting).
HDMI Audio: Can't make it work.
Tried to set it via audioCloverHDMI script:

File: audio_cloverHDMI-120.command_v1.0d
Release Mode
EFI partition is mounted
No HDMI audio codec(s) detected, continue (y/n): y
HDMI audio codec(s)
Device ID: 0x16590000 not supported
rm: /tmp/HDEF.txt: No such file or directory
Install AMD/Nvidia HDMI audio (y/n): n

Install finished, restart required.
To save a Copy of this Terminal session: Terminal/Shell/Export Text As ...

Using config.plist without inject intel, since it's native now. But I get "Intel HD Graphics KBL CRB 1536 MB" in About This Mac, the name is not a problem, just not sure if it's alright.

Laptop's audio is working just fine using the layout ID=13 in my config.plist.

I was able to get HDMI audio work just fine, but still have the problem with 620. When I connect the HDMI cable, my laptop screen goes black, and I only get it back when I restart the laptop.
My OS X is already checked with "Mirror Display", but still no change.

Your ioreg shows SMBIOS truncation. Set config.plist/KernelAndKextPatches/DellSMBIOSPatch=true.
You are not injecting ig-platform-id.
Your problem might be caused by inadequate DVMT-prealloc.

Did the changes you said, excepted about DVMT.. I'm booting using your plist and IntelGraphicsDVMTFixup.kext.
I realized something .. if I close the lid of my laptop after it turn on, and then open again after 15~20 seconds, and connect the HDMI cable, I do not face the problem of black screen on the laptop, and the HDMI works just fine.
But if I turn on my laptop, and connect, the laptop screen goes black and I can't get it back.

My files are attached.

Do you have legacy boot/CSM enabled in BIOS?

Do you have legacy boot/CSM enabled in BIOS?

I have Legacy Boot Mode.
But now I'm using UEFI.

I have Legacy Boot Mode.
But now I'm using UEFI.

Make sure legacy boot/CSM is enabled even if you're booting UEFI.
Don't forget to re-extract/re-patch ACPI after any BIOS update, BIOS option change, or hardware change.

Hey Rehab.
I re-patched everything with fresh new ACPI files.
Still have the problem with HDMI.
Also notes that if I connect the HDMI cable, and close the lid of my laptop with it connected, my TV blinks for a second, and when I open again, my laptop screen is working just the way it was supposed to to (Mirror Display), and I can connect and disconnect just fine, that works, my laptop does not goes black screen anymore.

If you do not have any more suggestions, I'm going to patch DVMT direct in BIOS to see if there is any change.

That and trying other ig-platform-id values are good next steps.
