When starting the television changes what plays in another Sonos room, check TV Autoplay and Ungroup on Autoplay before buying a separate speaker setup.
Test with a two-room group
Start music in the theater room and one other room. Turn on the TV with a known audio source and write down what plays in each room. Sonos documents TV Autoplay as a way to switch to detected TV audio and Ungroup on Autoplay as a way to separate the theater room from other grouped rooms.
Choose the behavior your household wants
If someone wants the kitchen to keep playing music while the living room switches to television, check whether the theater product has both options and compare with Ungroup on Autoplay enabled. If the TV room does not detect audio in the first place, check its TV connection before troubleshooting groups. Test a real transition rather than relying on the names of the switches.
