hey

i think in google have this video patch. is a personal thing. need some test

u can search with ur processor model

I already tried every I5-8300H/I7-8750H patch I could find. So strange I can't get it to work while it works perfectly in Windows and it's attached to iGPU not dGPU. 

This new motherboard shipped without serial numbers, could this be causing the problem? If I want my ethernet port to work I always have to spoof my MAC address through terminal so maybe HDMI doesn't work without motherboard serial or something?

I already requested if someone could help me recover MAC & Serials here: [HELP] ASUS N580GD - Missing Serial, MAC-address (& Unlock hidden settings)

I fixed it by going through all Bus-ID's. This way I found out that HDMI is on con2 Bus-ID 02.

The only thing that's not working yet is audio over HDMI. Adding this to iGPU doesn't do anything. I also tried to add my audio device under PciRoot(0x0)/Pci(0x1F,0x30) but that doens't work either.

try other layout id

add hda-gfx only in igpu patch

[Denisuu]

CX8150 only has layout-id 21 and 22 it doesn't work on either.

I only added HDA-GFX to the igpu patch and alcid=21 to boot arguments.

[MaLd0n]

i think in this case is about layout-id

in whatevergreen github have many infos about that
