    Hello, when you recommended that I try other mDPs I would shut down then unplug from port to another and still had no sound. If I try other mDPs while the system is on I get sound from 2 of the mDPs. Don't know what made me try it like this but I now can get sound when I unplug and plug from one port to another while the system is on. Definitely can work with that.

    I can't get my HDMI audio to show up as an output after trying multiple workarounds, including your script in this forum thread and the OSX ssdt installation v4 guide, as well as a few other guides in this forum.

    I'm using a Gigabyte UD3R x58a motherboard (BIOS V7), Xeon x5690 cpu, R9 280X graphics.

    In my S/L/E/ location there is no AppleHDA.kext present. Not sure if that's necessary for HDMI audio.
    I'm able to get audio from the audio jack on the motherboard but I'm trying to get HDMI audio sent to my surround receiver from my graphics card. Your help is very much appreciated.

    Here are my files related to the issue:

    I attached the missing files to my original post after realizing I omitted them by accident. Thanks for your reply and assistance. As far as I can tell, I only have one SSDT installed for the HDMI audio in the "EFI/Clover/ACPI/patched" location. I've spent quite a while trying to figure this out :banghead: ....Here are all of the files together. I noticed in the clover boot log, in the graphics section it shows "- HDMI Audio: ", like there is nothing installed nor active for that. Your help is greatly appreciated.
