Need help with HDMI sound on z490 aorus elite ac (Monterey)

[Ahmed Khalid]

Hello,
I have successfully installed Monterey 12.1 using opencore and everything is working fine except for my HDMI audio
I tried a lot of methods from different sites with no success (boot args using alcid, device properties with hackintool, Voodoo HDA, ...). Spent the whole week searching the forums and google with no luck
My sound is working through digital optic connection but it does not work on HDMI (Connected to my TV (Haier))

Motherboard z490 aorus elite ac
CPU: intel core i3 10100
iGPU: Intel UHD Graphics 630
Audio: RealTek ALC1200

Attached is my config plist, if anyone can direct me towards the solution and help to fix this problem I will be thankful

If you are talking about framebuffer patching, I have already tried that out with different layouts with no success.

If you can point me to a specific post that can help I will be thankful

I have found the following patch that fully enabled my HDMI

So here it is if anyone with the same problem and hardware can make use of it

Be aware that you will have 2 displays in display preferences
