Description of Issue

Roon doesn’t play to my NAIM streamer anymore. It says it does, but there is no sound and the progress bar of the track is not moving; it stays on 0:00. Roon does work in other audio zones via Win10 (1 via Nucleus->USB->iFI Zen DAC → amp and 2: from PC optical out → Argon DAC → amp.
However, Roon doesn’t work on my main system. No Qobuz, No Live Radio, No Local files from NAS, but the NAIM operates normally when using the NAIM or Qobuz app. So, the problem has to be Roon un combination with the Android app on my tablet (the latest Samsung one). Oh, and the app on my android phone doesn’t work either; here, there is a blue ‘light’ going back and forth quite fast on the track’s progress bar. All my apps and firmware are up to date.
Maybe I’m overlooking the obvious, but I would appreciate any advice.


Try rebooting everything.

Ah! Rebooting the Nucleus and the router seems to have done the trick! Because they worked fine in the other audio zones, I never thought that the problem could lie there. Thanks!
