Control Center does work with Sonos Soundbars, provided Sonos is connected directly to your TV (Control Center has no audio outputs).
Sonos can be controlled by Control Center via IP. In order to use IP control, Control Center must be on the same network as your Sonos.
Control Center can perform basic controls with Sonos through IP controls. Sonos keys are mapped to the following Control Center buttons:
|Volume Up||+ Volume Up|
|Volume Down||- Volume Down|
