here you go... its for the GPU + GPU-Audio. This Problem with the system-entries are in my systems only in BigSur... Catalina is ok with Device-Properties...

Thanks, do you have an example SSDT that I could take a look at?

Yeah I vaguely remember having an issue with Big Sur and device property renames. I had to manually define GFX0 and HDAU even though WEG takes care of it. HDAU device property worked before the SSDT but renaming the GFX didn't.

That has done the trick, thank you. Although while doing this I did notice that I forgot to remove my Device Properties entry and once the SSDT is applied, the Device Properties once again work and overwrite the contents from the SSDT. So, you can either remove them from Device Properties or just leave it in both - I haven't found any adverse conditions from doing that but shout if that's a bad idea. ;)

Cheers

Looking good now. :thumbup:

How do you see all the PCI?
Can you share your EFI folder?

1) See the picture above - that's system-report.
2) Use Hackintool
3) Use IORegistryExplorer.app

Are you sure it's that simple? :crazy:

I may have been doing Hackintosh since 10.9
But it has always been with the help of the community
Especially on the X99 - X299 platform
And I never wrote SSDT myself or anything like that

Do you have a link to the video guide?

nice and easy

use hackintool to generate this for you

mount your efi and it can even add the info into your config.plist, nice and easy!

Sure - I just updated the EFI attached to my Asus PRIME X299-A II post. Its a combination of Device Properties as the posts above mention and SSDT's for the GPU's as Big Sur doesn't seem to apply the Device Properties entries correctly for both the GPU and HDMI/DP Audio devices on the GPU's. Pretty straightforward once you've done one or two devices, just rinse repeat. :thumbup:

Edit: Also don't be too intimidated by writing your own SSDT's, I'm no expert in ACPI, its usually just a case of looking at an established method and adapting to your ACPI paths and names by checking another tool like IORegExplorer, Hackintool or a DSDT dump from your board using something like MaciASL which is great for checking your SSDT too, if there's errors in the syntax it'll tell you. Its not too bad, give it a go. :)
