The Spatial Sound on windows10 "DTS Headphone:X" and "Dolby Atmos for Headphones" don't work in Vulkan API mode, but those work fine in DirectX 11 API mode.
Hey HYJ_Account, thanks for getting in touch and bringing this to our attention.
I've had a look however it does not seem like this has been brought up before, therefore for reproduction purposes, can I just double-check if this is the case in every session on Vulkan API or are there any particular steps you take that can create the issue?
Let us know!
