NVIDIA HDMI Audio Not working

[kurbads]

There are two slots and the card is in the lower one.

Here is a photo. After buying and discarding computers over 40 years, I finally gave up and decided that it was not worth it to put it in a case. The mobo just lays there under my table until it will outdate itself.

I have liquid cooling and an aquarium pump to make it as quiet as possible. That was also a choice of GTX 750 Ti because it has a large ventilator which rarely hums.

Switch the GPU to PCIEX16_1 Slot and provide a copy of IOReg.

Also, are you using HDMI for display? If so, are you using any sort of Converter/Adapter?

Does your monitor support HDMI/DP Audio?

I am using HDMI for display for now. Yes display supports HDMI audio, that is why I boot into Windows lately because it supports it OOB.
Normally I would use the HDMI for my projector via 15m long HDMI cable. And I use the DVI out for video.
My amplifier died.
I used to use a USB DAC to get sound out of it but now it is dead and I look into buying a new one or fixing existing one but in a meantime, I would like the HDMI sound to work.
I will reboot with the card in other (16x) slot and give you the ioreg.

Ok, and that is my IOREG with the card up.

And that is me, turning the computer on after it has been shut down

As this Motherboard supports UEFI, it would be much better to switch to OpenCore, instead of fixing the existing Clover configuration.

Booting what? I don't boot installers on macOS nor OSX. Soo, what does that sentence mean?

"OS X/macOS Installer" of course. You can only boot if you have installed it. To install it, you'll have to boot the installer first. Here, the installer means the Bootable USB.

Well, that's offensive.
