HAL MS-6 users are trying the system with Roon and the first system is running as a Roon Endpoint.
During this, Microsoft has done an update to the system video display device driver that has to be loaded for Roon to load and run. Early MS-6 units may not have that driver loaded as it was not needed for either Foobar2000 or JRiver MC27 for music playback.
If you are going to run Roon, let me know and I can step you through the check to see if the Intel video driver has been loaded in Windows 10.
All MS-6's being sent out now will have the video display driver loaded for Roon to load and run correctly.
