AppleALC HDMI audio doesn't work NVIDIA

Hi all.

I decided to try switching from VoodooHDA to AppleALC, I successfully got the ALC887 to work, but I can't get the sound over HDMI of my graphics card (GTX 1050 // GP107GL) to work.

At first I decided to try and copy the patch from Controllers.plist and copy it to my OpenCore config, but unfortunately that didn't work. [image]

Then I decided to try writing "external-audio" for GP107GL in my OpenCore config. This didn't help either. [image]

Using High Sierra 10.13.6 and the latest NVIDIA drivers.

Can anyone explain how to get HDMI audio to work properly?
