Set up a new Sonos system 2 weeks ago consisting of 3 Sonos One units supported by a Boost. Worked fine for 2 weeks (save set up was difficult). Now one of the Sonos One units no longer emits any sound. It’s fully connected to the system, I’ve even restored it to factory settings and re added it to the system but no sound. No chime sound either when I press the infinity button.
it is not WiFi connectivity issue as other 2 speakers work fine and in same room.
