Updated 07/3/2018. This solution works in High Sierra 10.13.6 as well as several previous versions of MacOS. I didn't create the tools I only figured out how to use them. Credit for the kext goes to andrejkw at macrumors. Your mileage may vary but this is the easiest solution I've found. I've used it for years & its worked for many others. Definitely worth a try.

1. Download package located here https://www.dropbox.com/s/8hay1m0rec93vvo/HDMIAudio-1.0.dmg?dl=1
2. Mount HDMIAudio-1.0 disk image
3. Mount your EFI partition. You may need to use Clover Configurator or similar tool to do this.
3. Copy HDMIAudio.kext from the HDMIAudio disk image to EFI/Clover/Kexts/Other
4. Reboot. Clover may hang on the initial boot attempt, if so a restart of the computer should have you up and running.

There you have it, a simple file copy.
After the reboot I had working HDMI Audio.
*If you don't see any audio devices after reboot. Download and run AudioCloverALC command by toleda
https://github.com/toleda/audio_CloverALC/raw/master/audio_cloverALC-130.command.zip

This may help to finish off the install.

If you're confused, there is a quick rundown in this video. *VIDEO IS OLD. COPY KEXT TO "OTHER" FOLDER!
*Don't forget to select the proper output! System Preferences/Sound/output or hold the Option key while clicking volume icon.

So now you have HDMI audio, but what about volume control? OSX doesn't support volume control of HDMI devices natively. Use one of the utilities below to enable it.

I'm not sure which cards this works with. I didn't write the tools, just figured out a way to use them. Ultimately its a simple download and file copy. I'd recommend giving it a try.
