After having my new Intel Nuc hooked up to my DS via USB for a day, I could no longer get sound. The DS display showed a red dot, indicating offline. The DS also disappeared from the
Roon zone list. Also, the Roon app was showing rapidly changing currently playing selections. First I rebooted my Nuc. Then I unplugged and replugged the USB cable. Then I turned off and on the DS. Still USB was offline. Then I fully powered down and restarted the DS via the back rocker switch - that worked! The DS is updated to Snowmass. The Nuc is fully up to date. Please advise why this happened and if a DS firmware update is needed.
Update: I think both times the connection was lost, I had tried to select an internet radio station in the Roon app. Definitely the second time I selected it, the WQXR stream, I heard a little blip, then the connection was lost as the display showed the red offline dot.
