SSDT GPU (Graphics Card) Injection

[thenightflyer]

As noted in my post above (#314), I did try shiloh's method, made a few attempts to generate SSDTs to fix this but I was not successful. But @gialeocomopardo and @kgp have 1080 cards, and they have been successful. However, they have their cards in the very first slot (closest to the CPU), and mine was in a different slot, and I thought that might be a problem (but as it turned out that was not the case). Also we all have the same board: X99-A II, so that might be an issue too for those who have a different board. Giacomoleopardo has a 6900k in his systems and KGP and I have 6950x cpus. The only final thing I did that was different was I plugged my display port cable into a different port on the back of my card. I can't believe that might have been a cause of the failures, but maybe.....

So you have a display port cable and not an HDMI like me...

My card has three display port connections and one HDMI. It's an EVGA 1080 TI classified.

I know...but at the moment you use the display port, right?

Yes, second one from the top...

You know, VoodooHDA was working fairly well. It had just a few things it did that I didn't like, but they were very minor. For this to work, you have to have either Toleda's script working or AppleALC working on your system (analog). Then this patch can work. I think you probably know that, but I thought I'd mention it, just in case.

Ahh that's why your audio worked. I use HDMI cable..and with HDMI cable and some 10xx cards and latest Nvidia Drivers there's no audio at all...except with a DP to HDMI adapter

I see. I also found a $10 utility to control the audio levels (and it has an equalizer too). Soundcontrol by staticz. Worked with Voodoo too, just slow to initialize/load. But somehow I think you probably have that covered.....as I recall, you do a lot of audio work, right?

Well, all the best in working this out.

Do i understand that correct, the device path would be:

\_SB.PCI0

So the closest Patch would be

Disable PCI0.PEG0.PEGP.txt ?

into_all all code_regex Name.\(\\_SB_.PCI0.PEG0.PEGP._STA,.*\) remove_matched;
into definitionblock code_regex . insert
begin
Name (\_SB_.PCI0.PEG0.PEGP._STA, Zero)
end;

So i need to rename the path in it to:

\_SB.PCI0

Is this correct?:

into_all all code_regex Name.\(\\_SB_.PCI0._STA,.*\) remove_matched;
into definitionblock code_regex . insert
begin
Name (\_SB_.PCI0._STA, Zero)
end;

I have made a git style repo using Gogs for varies SSDTs for AMD GPUs at https://ddi.hopto.org/gogs-server/henry.brock/AMD_SSDT you are more than welcome to add to it as you please.

I install High Sierra on old H55N-USB3 with GT640 and run but i can't get HDMI sound.
Audio_cloverHDMI not install because not found NVIDIA, it's call PEG0@3

It's impossible for me change name because i not found PEG in origin/aml. Never touch ssdt or aml files
Please, someone can guide me?

how to handle something like this:

Therer is no Device name above the pci-bridge ? please
