Audio through HDMI support?

I'm currently using MBP 15" 2016/Devil Box/Gigabyte 1080Ti and all graphics functionality seems to be fully working with fresh macOS 10.3.6 and macOS-eGPU.sh script.
However, it is not possible to have the audio passed through the HDMI to my external monitor, which has built-in speakers. It seems the driver for the audio has not been installed? (if I go to System Information > PCI it shows the 1080Ti, and an unidentified "Audio Device" with "No" as the Driver Installed status below it).
What should I do so that I can get the audio working on my external monitor?

Audio passthrough over HDMI and DisplayPort comes and goes depending on the build. You can try an older Nvidia web driver version and see if it works.

I thought the Nvidia web drivers are tied to the build number of macOS?

I'm also interested in this. I seem to remember audio working in a previous version, but now it doesn't show up in macOS.
