For the 4th time, no HDMI audio dsdt edits results in no HDMI audio.
See post #1, edit you dsdt for HDMI audio.

Reply with HDMI audio edited dsdt.

I downloaded the dsdt and started from scratch. This is my edited dsdt:

Thank you again for your patience with me. I used the awards 5 series option; i hope that was correct. But still no hdmi. Totally a noob at this for sure just looking for some desperate help

still no hdmi.

No IOReg, no idea. It is the only way to see what you did and why it is not working.

SOrry about that- there you go

 

[toleda]

there you go

IOReg is showing and edited PEG0; do you have an ssdt installed? If yes remove. If no, there is another dsdt somewhere in your system, remove.
dsdt/PEGP is not correct:
find:

            Device (PEGP)
            {
                Name (_ADR, 0x00030000)

Replace:
Name (_ADR, 0x00070000)

Reply with edited dsdt and new IOReg.

 

[ghelanijimmy]

Replace:
Name (_ADR, 0x00070000)

Ahhh that worked!!! Changing it to 00070000!

I didn’t change anything else except I had ssdt options in clover such as generate p and c states. I didn’t have any extra dsdt’s.aml or ssdt’s.aml

Thank you so so very much!

I have a question: why did I have to change it to 7 instead of 3? I just want to learn and understand more about this if that’s not too much trouble to ask

You’re a real hero! Cheers! And thanks for putting up with my noobness haha

why did I have to change it to 7 instead of 3?

IOReg shows the graphics card at PEGP@7. Your sound card is in @3. Likely graphics is not in a x16 slot and the sound card (x1 or x4) is.

Thank you for the explanation; weird thing is my graphics is definitely in a x16 slot (just checked) and my only other sound card that doesnt work with my hack (or i dont know how to) is my x-fi bravura 7.1 card. the other sound devices are onboard on my ex-58. But i get it now kinda of. slowly getting the hang of understanding this.

Thank you!

To summarize what I did:

Hdmi Audio with Clover and Nvidia Web Driver: 346.02.02f03 and OSX 10.10.4
Boot with the Option:
DSDT=Null
Open MaciASL
Go to MaciASL/Preferences/Sources, add http://pjalm.com/repos/graphics/ (add http://pjalm.com/repos/mainboard manufacturer)
Klick Patch, select „Generic Discrete Graphics (AMD/nVidia)“, replace

Store (Package (0x0E) {\n
"AAPL,slot-name", "Slot-1",\n
"name", "Display Controller",\n
"@0,connector-type", Buffer(0x04) {0x00,0x08,0x00,0x00},\n
"@1,connector-type", Buffer(0x04) {0x00,0x08,0x00,0x00},\n
"@2,connector-type", Buffer(0x04) {0x00,0x08,0x00,0x00},\n
"@3,connector-type", Buffer(0x04) {0x00,0x08,0x00,0x00},\n

with

Store (Package (0x12) {\n
"AAPL,slot-name", "Slot-1",\n
"name", "Display Controller",\n
"@0,connector-type", Buffer() {0x00,0x08,0x00,0x00},\n
"@1,connector-type", Buffer() {0x00,0x08,0x00,0x00},\n
"@2,connector-type", Buffer() {0x00,0x08,0x00,0x00},\n
"@3,connector-type", Buffer() {0x00,0x08,0x00,0x00},\n
"@4,connector-type", Buffer() {0x00,0x08,0x00,0x00},\n
"@5,connector-type", Buffer() {0x00,0x08,0x00,0x00},\n


Klick Apply, Close, Compile. If there is no error, go to File/Save as, select File Format „ACPI Machine Language Binary“ and Save as „DSDT.aml“. Copy this file to the ESP-Partition where Clover resides, into the folder EFI/CLOVER/ACPI/patched.

Et voila, Display Port and Hdmi Audio of the GTX970 work.

Problem reporting:

1 - With dual Graphics Card I can get HDMI Audio just from the first one. Do I need additional/alternative DSDT patch?
2 - Yosemite 10.10.4/Asus P9X79 WS/BIOS 4802/Intel Xeon E5 2687W V2/Dual MSI Radeon R9 280X (pci-e 1 + pci-e 4 —> dual x16 Pci-e 3.0) with one 27” Apple Cinema Display each (DP version)
3 - UEFI Clover install method/SSDT generated by PikeRAlpha’s script/DSDT patched by custom toleda_hdmi_5series
4 - Attached IOReg native + IOReg with first GFX HDMI
5 - Copy of Console - All Messages attached
6 - Native System/Library/Extensions/AppleHDA.kext (Clover config.plist patch)
8/1 - EFI/CLOVER/config.plist
8/2 - EFI/CLOVER/misc/debug.log

Yes.
Rename NPE7 to PEG1 (2x)
Paste code over PEG1:

          Device (PEG1)
            {
                Name (_ADR, 0x00030000) 
                Method (_PRW, 0, NotSerialized) 
                {
                    Return (GPRW (0x09, 0x04))
                }


                Method (_PRT, 0, NotSerialized) 
                {
                    If (PICM)
                    {
                        Return (AR27)
                    }


                    Return (PR27)
                }
                Device (GFX0)
                {
                    Name (_ADR, Zero)
                    Name (_SUN, One)
                    Method (_DSM, 4, NotSerialized)
                    {
                        If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }
                        Return (Package()
                        {
                            "hda-gfx", Buffer() { "onboard-1" },
                        })
                    }
                }
                Device (HDAU)
                {
                    Name (_ADR, One)
                    Method (_DSM, 4, NotSerialized)
                    {
                        If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }
                        Return (Package()
                        {
                            "hda-gfx", Buffer() { "onboard-1" },
                        })
                    }
                }
            }

FYI, to inject an AMD framebuffer, modify GFX0 as appropriate:

           Device (GFX0)
            {
                Name (_ADR, Zero) 
                Name (_SUN, One) 
                Method (_DSM, 4, NotSerialized) 
                {
                    If (LEqual (Arg2, Zero))
                    {
                        Return (Buffer (One)
                        {
                             0x03                                           
                        })
                    }


                    Return (Package (0x0C)
                    {

                        }, 


                        "@0,name", 
                        Buffer (0x0E)

                        }, 


                        "@2,name", 
                        Buffer (0x0E)
                        {
                            "ATY,Dashimaki"

                        }
