I have a new Playbar connected to a Vizio TV. No other speakers are paired with it. Other Sonos speakers in the same house, but not in the same room, are Play 1, Play 5, Amp, and Connect Amp; Volume on PlayBar increases on it's own when source is streaming TV (ie, Netflix), but not when playing music. Only remote in use is the Roku Enhanced remote. That remote will control the volume (we have to use it every 10 minutes to turn the volume back down).
