I have an old TV in my family room which will not connect directly to my Sonos Beam, so I have optically connected the Beam to my Sky HD box. I have a second TV in my kitchen that uses a magic eye connection so I can control and watch Sky programmes remotely via the coax out connection from my Sky box to my kitchen TV. When I switch on the Sky box from the kitchen, the Beam comes to life in the living room and plays the Sky content, even if I have previously muted it. How can I mute the Beam so that it stays muted until I explicitly unmute it? When I submitted this as a question to the Sonos team, they suggested disabling autoplay, but as I understand it this would require that I always have a smart phone to start the Beam playing in the family room, which is overkill. I'd love to see a feature whereby the box stays in the state you last left it (maybe with an upper volume limit so you don't risk breaking your ears when you unmute)
