I have a Sonos Beam in my living room in a group with two Gen 1 Sonos One speakers and a Sonos Sub. I have had Alexa enabled since I initially setup this system.
All had been working well but suddenly, Alexa will not stop or pause playing by voice command. I can say "Alexa, play NPR" and it will respond properly. I can say "Alex Louder" and "Alex Lower" and the volume will adjust. But when I say "Alexa Stop" (which is what I've been saying since day one) or "Alexa Pause" it will simply make the command chime and keep playing.
Also, the Beam is working properly but in the Sonos app, I don't specifically see the Beam listed as a speaker. I think it might simply be labeled "Living Room?" I'm not sure if I should see the Beam specifically?
I tried to remove Alexa and reactivate it but I got completely confused and I'm not sure what I accomplished.
I'm now back to square one, with the same symptoms as described above.
I have an Echo Dot in another room that responds normally to Stop and Pause commands.
