I have spent thousands euros in sonos components both for home and office.
Both environments play under high speed network.
I’m used to listen to deezer favourites tracks (2300 songs) in a group of two/three rooms.
There is always a problem: if electric power is down for a while any reasons, Sonos forgets everythings, the room groups, the playing playlist, all. You need to group again the rooms, select the playlist and so on.
If this was not enough, most of the time, no, all the time, sonos skips tracks with som error (incorrect encoding or network not responding).
When I try to ask support the solution is always, always, please try disconnecting the router, keep disconnect then restart.
Not even windows at his best had so useless solutions.
