Is there a way to switch from Music to TV, or vice versa, using a remote control (i.e. outside the Sonos app). In our Living Room with a Vizio display and Sonos Playbar we are often listening to music while the TV is on. At times, we'd like to quickly switch to the TV's Audio and grabbing the remote would simply be more convenient than finding an iPhone and firing up to Sonos app. Is there a way to program a remote to control the Sonos Playbar Audio source?
