Hello - trying to get some info on setting up the Arc/Sub with my TV and also using for general music listening. Obviously, I will have the Arc connected to the TV and when watching TV would expect the Arc and the Sub to play (I will not have any other Sonos speakers playing when watching TV). I also have 5 other Sonos speakers throughout the house that I play music through. I group them different ways at different times depending upon the need. My questions….1 - can I group the Arc and Sub like any other Sonos speaker so they play when I’m listening to music? 2 - can I group the Sub like any other Sonos speaker even if I don’t have the Arc included? 3 - assuming I can do #1, what’s the process to revert back to only the Arc & Sub when I’m ready to watch TV? Is it just changing the group that’s playing? Thanks a lot.
