Compatible with Vega 64?

[NathanR-85]

I'm making the SSDT patch but ran into something:

While finding the name and path of my Graphics card in IORegistry Explorer, I see a value but also a bridge, which the guide says to watch out for, and the two Terminal commands return nothing, so there's multiple red flags according to the guide.

My IORegistry: https://ibb.co/P9M8tBm

But I have a Sapphire Vega 64 which is fairly common. Will this SSDT not work?

If it helps, here is the audio device in Hackintool: https://ibb.co/XCrJ6QY

Thanks!

You need SSDT-BRGO as well (or integrate BRG0 device in the SSDT)

Hello :) I can put both files in but want to make sure I’m making the SSDT correctly.

Well then merge them both together, check and adjust the ACPI paths (the default of SSDT-BRGO suits your case) and then test it.

I'd really appreciate any help. I don't know how to merge them together or adjust the ACPI path. I sent a screenshot above, so does that mean the ACPI path is PEGP@0?

Like this. Adjust the paths as needed.
