My apologies @peter_richardson, I meant to ping @Bill_Labus with that response!
The x86 installer should work fine and testing has met performance benchmarks. The issues are with the GUI, and you’re broadly familiar with them already for this thread: Invisible search text issue on Windows PC Roon app [Fix in Test Build, See Thread]
So broadly speaking, Snapdragon-based players are supported by Roon as Windows devices, but they’ve faced some hiccups that were in the pipeline until very recently. These issues were enough to fundamentally break the user experience; as a result, we issued communications advising users to temper expectations for Snapdragon-based Surface/Surface Pros for now. The invisible search bar was the main bug, but there will be scrolling issues and other visual artifacts with font rendering.
