Ethernet streaming and occasional white noise on Windows

[AlexS]

The dB sign turned orange when it happened, if I pressed pause on the iPad the noise stops and the dB sing turns white again. If I hit play it turned orange and the noise is back.

Morten, are you referring to the Devialet iPad app, or Devialet's display? What's the significance of orange, do you know? When everything's OK, what's the color of the dB sign, when you stream music?
You mentioned that when you changed music, things were back to normal. In fact, they were not. Several people noticed that once the problem happens, it's more likely to happen again, unless you you restart AIR AND the player, perhaps, even reboot the PC.

If you run PC continously, I'd restart AIR and the player every day. If you put your PC to sleep, make sure you always quit AIR and the player before doing so (or else when you wake the computer up).
