Well I previously attached my problem reporting files...
HDMI audio pre-requisite is audio using patched AppleHDA.
You're using VoodooHDA.
So... work on patched AppleHDA first.
See FAQ.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/

Your ioreg shows HDMI device connected to the 0105 connector and ig-platform-id 0x19160000.
The 0105 data in 0x1916000 is:
01 05 09 00 00 04 00 00 87 01 00 00

So...
Find: 01 05 09 00 00 04 00 00 87 01 00 00
Replace: 01 05 09 00 00 08 00 00 87 01 00 00

They are not in ioreg. The data I show is from the framebuffer kext binary.
I used the ioreg you attached only to determine which connector your external display was connected to and which ig-platform-id you were using.

If you have a question regarding anything in your configuration, attach all "Problem Reporting" files as per FAQ.

These are my new problem reporting files.
Thanks
The patch is present, and may have had an effect.
You should check connector-type under AppleIntelFramebuffer@1 before you connect the monitor.
But it won't matter anyway as you still have VoodooHDA installed.
And other HDMI audio requirements are not met ("hda-gfx", "layout-id" injection)
