I have Sonos everywhere in the house and one room has an old Bose lifestyle surround sound system with 5 speakers and sub. I have a Sonos port and if I turn the Bose on, change to the right input, I can play Sonos. 
 

but it’s the only room in the house that doesn’t just turn on. I have to go into the room and turn on the Bose system first with the remote, wait for it to boot up, then switch the input. 
 

it’s a hassle. Anyone know of a better way if I keep the Bose?
