Sometimes when I ask my Echo Dot Alexa located in the Kitchen to play a station on the Kitchen Sonos 5, she answers, "Station playing in Kitchen" on my Sonos Move in another room on the other side of the house. The station does play on the Sonos 5 in the Kitchen. The same thing will happen if I ask her about the weather or time. This is annoying because we can't hear her response.
I tried logging out of both Sonos and Alexa, resetting my router, updating Sonos, cycling power and even changing my Amazon password. I also have a Sonos 3 in the Bedroom and a Connect:Amp in the Living Room. I've installed Sonos Voice Control on my Sonos Move. My setup worked fine for about a year and just started this problem about 2 months ago.
