Still no joy. I managed to get one Tidal work to play in its entirety. The next track I had placed in the queue (different album, also a Tidal import) stopped after a few seconds when the ID41 zone was dropped. Now nothing Tidal will play through, like it's been doing for me.

This after running a new hardwire from our router to a 5-port switch off of which the MC200, QNAP and 861 are connected. I also power cycled the MC200 and 861 before this last trial. That one work did play through. Thought I had it nailed. Then the problem resurfaced.

What else can I try?
