I had similar challenges with supported formats via HDMI due to the Intel audio driver in a NUC7. It would just give me “initialization” errors when it tried to convert DSD to PCM (my receiver doesn’t have native support for DSD.)
A workaround I found was to install ASIO4ALL and use it instead of WASAPI (details here.) It sounds like you may already have a solution, though, so hopefully you don’t need this and can just enjoy your music
