Previously you stated all works even with HDMI output. What changed?

Try removing these arg

Before the migrate to Mojave worked, and after the migration, this is the only thing that I did not check. I apologize for being misleading.

remove this key, but after plug HDMI have hang and KP report after reboot

Spoiler

Here is my config: catmat-7480-v7.zip

But now i broke sound in headphones. cant find reason why, try layout 13,56 , but no luck

SSDT-ALC256.aml in ACPI/Patched , CodecCommander.kext in S/L/E , layout 13 , and no sound in phones. Then i plug phones in jack, sound off (speaker) but no sound in phones. 

@Jake Lo, did you have any advise ?

I want to share my observations about touchpad issues.

I used a bootpack from this tread to boot Mojave 10.14.3 on my SkayLake based Latitude 7480. Unfortunately I don't remember build version of Mojave.

The trackpad did not worked until DarwinFix was applied in Clover config. I installed Mojave update version 18D109 later. After update I got Touchpad broken. After some time I removed DarvinFix and got the touchpad functionality back 🤪. So, to me the track pad issues (when VoodooI2C kext work for some peoples while it doesn't work for others) is also depends on OS build version and ACPI patches in clover.

 

Now I wonder if you guys managed to get backlight adjustment work properly. I use AppleBacklightFixup.kext but the best I could get was 100% brightness, with a non-working slider :-(. Actually the backlight has 2 states depends on the slider position - Full brightness and no backlight at all. I have followed AppleBacklightFixup instructions down to the letter but no success.
