I have a new pair ERA100, set up as a stereo pair with a sub-mini, and have the following two problems:-
No 1: Playing music in more than one zone, the pair sometimes drop out of the group unexpectedly. They can be added back immediately and without any problem (issues like this in the distant past have been “networky”, and the missing zone had lost its connection to the Sonos network and would not add back without some hassle).
Could this be related to a keyboard shortcut that drops a zone from a group? I am not sure, but it seems to happen when I am typing on the keyboard of the Windows computer with the S2 client.I am not in the Sonos software when typing and this cause/effect may be my imagination.
No 2: Whether grouped with other zones, or playing on their own the right speaker sometimes goes dead. It is still showing up as a device in the software settings, but unplugging the mains seems to be the only way to make it pair back up. It ha#e only happened with one of the pair.
ERA100 can’t be ethernet wired so can’t test to see if this is the problem.
No 2 above makes me wonder if there is a manufacturing defect. Thess are only a few days old and both problems have been present from the start.
