2. Attempted HDMI audio and not working; remove all previous attempts​

Something else was first and it ensures all other attempts will fail.

Thats weird, i replaced the whole EFI folder with an untouched one, created a new info.plist with 0 patches and it keeps showing me this information. I'll re-install the system from scratch tonight and try again.

Thanks for your help

I tried the new SSDT, no more glitch but HDMI/DisplayPort Audio still not working.
In IORegistryExplorer, PEGP has a sibling pci10de,fbb@0,1 instead of HDAU.
Here's the new ioreg file.
