What is it doing for you?
running cloverHDMI has installed SSDT-HDMI-NVIDIA-PEG0.aml
I answered 'yes' at the 3 questions but not sure of that ....

When restart :
Do not see HDMI sound device
apparently no graphic issues (expect a little longer black screen at shut down)

My flies are attached

Many thanks !

Still no HDMI devices
ssdt fix did not work.
Choices:
1. Edit dsdt, remove 5 lines as shown:
Code:
        BNUM,   8,

                Device (D05B)
                {
                    Name (_ADR, Zero)
                }
Compile, save, restart, reply with new files.
2. Restore NvidiaGraphicsFixup.kext.
If no HDMI audio, post to NvidiaGraphicsFixup.kext developer site.

Restored with kexbeast
still no HDMI devices
Is this the good place to post my NvidiaGraphicsFixup.kext problem : https://sourceforge.net/projects/nvidiagraphicsfixup/support?source=navbar
I saw that a NvidiaGraphicsFixup.kext 1.2.2 is ready (mine is 1.2.1) -> should I try it ?

1. Edit dsdt, remove 5 lines as shown:
a little difficult for me
what tool is used to edit and compile simply on 10.13.2 (I tried dsdt editor but asked me an older java version) ?

Hi toleda,

Thanks for your reply.

Changed graphics card to other slot, removed HDAEnabler1.kext, restarted and ran cloverHDMI (which passed!)

Now the Sound>Output list is empty, so no sound through headphones or HDMI.

I've attached new files.

Thanks again.

Post #1/III. Tools/4. MaciASL
Post #1/IV. Problem Reporting/8. MaciASL ...
OK many thanks !
I guess it will take a while before learning how to disassembly/modify/compile - Will let you know if I success the opération !

Should I first disassembly SSDT-HDMI-NVIDIA-PEG0-D05B.aml with MaciASL or need to extract something before ?
