No Audio HDMI or Internal on 6i5SYH NUC (Big Sur)

I've gone through many threads and guides and can't figure out why HDMI output won't work. Internal audio isn't working either, but only need HDMI. According to Swoosh1234's guide, " HDMI Audio is fixed by using FakePCIID + FakePCIID_Intel_HDMI_Audio (RehabMan-FakePCIID-2018-1027) "

I've got those Kexts and have added the info in device properties and still doesn't work. I also tried using the config.plist there with my build and audio still didn't work. Finally, I tried downloading Swoosh1234's EFI onto a second USB, but that refuses to boot on my NUC.

Link to my config.plist
