Wrong. You are not able to read, understand and follow the guide in the originating post fo this thread, are you?
You should basically do the following:
1.) Download and copy the EFI-Folder contained in EFI-X99-10.13.6-SU-Release-iMacPro1,1-121218.zip to the EFI-partition of your system disk (I hope you know how to open an EFI-partition). It already contains a fully valid Clover boot loader distribution! So there is no need to additionally install Clover.
2.) Add properly adopted TSCResetAdjust.kext and James-Asrock-X99M-Killer-3.1-iMacPro-XHCI-15port.kext in /EFI/CLover/kexts/Other
3.) Download and implement Lilu.kext, AppleALC.kext and Whatevergreen.kext in /EFI/CLover/kexts/Other
4.) Open the config.plist contained in the EFI-Folder-Folder with Clover Configurator:
a.) Complete SMBIOS credentials in section "SMBIOS" of Clover Configurator, following the guide in the originating post of this thread, i.e. add a valid serial, board serial and SMUUID.
b.) Go to section "Kext and Kernel patches" of Clover Configurator. Check "KernelPM" and enable "XCPM_core _scope" kernel patch, as the MSR register on your motherboard seems locked.
c.) Change FakeCPUID from 0x040674 to 0x0306F2
d.) Enable and change "XCPM_bootstrap" kernel patch to
Code:
Find: 89d804c4 3c227722
Replace:89d804c1 3c227722
e.) Enable and if necessary adopt the FredWst DP/HDMI patch: Verify that DE10EF10 is the device-ID of your GPU, otherwise substitute DE10EF10 by the device-ID of your GPU
f.) Go to section "devices" of Clover Configurator and select correct ID for audio injection.
g.) Go to section ACPI and enable the following ACPI replacement patches
_OSI -> XOSI, EC0_ -> EC__, H_EC -> EC__, HEC1 -> IMEI, IDER->MEID, LPC0 -> LPCB, FPU_ -> MATH, TMR_ -> TIMR, PIC_ -> IPIC, _DSM -> XDSM
h.) Save your modified config.plist
5.) Download and copy SSDT-DTPG.aml, SSDT-X99-HDEF.aml, SSDT-X99-Nvidia.aml to /EFI/Clover/ACPI/patched. Open IORegistry Explorer. Edit SSDT-X99-HDEF.aml and SSDT-X99-Nvidia.aml with MaciASL. Verify and if necessary
adopt and modify ACPI path and
ACPI replacements and
respective DSM details in
HDEF,
GFX0 and
HDAU SSDT implementations
in concordance with your IOREG information!
This small guide might help you in properly performing the latter. Following your "PCI" snapshot above, you did not properly modify SSDT-X99-Nvidia.aml, and consequently both GFX0 and HDAU are not properly implemented in section "PCI" of Apple's system report. In consequence, HDMI/DP audio does not work!
6.) Reboot your system
7.) Now go to system preferences and audio settings and enable "Show Volume in menu bar". Go to the audio symbol in the menubar and switch audio output to your monitor (in my case LG HDR 5K)

If you implemented everything properly, you should have a fully working USB and audio configuration. Verify in IOREG and under Section "PCI" of Apple's system report that HDEF, GFX0 and HDAU are properly implemented!
If you are still not able to succeed,
upload your
EFI-Folder +
IOREG.save +
"PCI" snapshot of Apple's system report, that others are able to remove remaining issues.
If you use the EFI-Folder of
@JamesKI instead performing all points outlined above, please directly address all open questions to
@JamesKI and ask for his help and assistance!
If you are not able to understand the above due to language problems, there is absolutely no way to proceed here. In the worst case, Google Translator might help.
Good luck.
