Nvidia Shield TV and Roon Remote

My current plan is to have Shield w/Emby connected to XMC-1 pre/pro via HDMI for video, and use Roon for music (ROCK & ethernet to USB box).,

I have a win10 pc built like a gaming PC for Emby Server and Big Drives for video and music. ROCK will access music files of the PC which should look like network attached drives.

I am hoping I can also connect ROCK via HDMI to another input on my pre/pro for MC music.

I currently use the win10 PC as a HTPC with USB to pre/pro for stereo music and HDMI to pre/pro for video and MC music using JRiver and Emby.

I have a laptop, Surface, ipad and phone as control options.
