Works with Microsoft driver, but not the Nvidia driver. Passthrough BITSTREAM audio correctly displays as ATMOS on soundbar (expected since PASS THROUGH).

Question - Bitstream via HDMI from nVidia or AMD GPUs ...
https://www.avforums.com/threads/bitstream-via-hdmi-from-nvidia-or-amd-gpus.2180472/
I received an email from nVidia today to state that my graphics card (nVidia GForce GTX 1060 6GB) only outputs sound in PCM. I've asked them if any of their GPUs allow audio to be output in bitstream. I'd happily move to AMD if the RX 580 / Vega 56 did allow bitstream.
Cant get 5.1 audio over HDMI | NVIDIA GeForce Forums

The sound-card in there is an Asus Zonar DGX. It outputs films in 5.1 DTS via Optical Digital due to Bit-Stream compression, but not games, due to their uncompressed HD audio, so I have to resort to using Dolby Pro-logic surround sound approximation for games via my sound bar.
Force HDMI to carry 5.1 Dolby or whatever - Windows 10 ...
https://www.tenforums.com/sound-audio/148247-force-hdmi-carry-5-1-dolby-whatever.html
The Nvidia card has a display port to HDMI adapter, which I use to connect to the HDMI audio extractor which sends the HDMI on to the HDTV. But all the sound it ever gets is stereo. I plug a fireTV stick into the HDMI splitter and I get 5.1 Dolby out of the sound coaxial port on both the splitter and the HDTV, so the hardware works.
