I have a den set up that has 5 speakers and an additional 2 zones with 2 speakers each in the living room and outside by the pool. I'm able to play music via Bluetooth to the main and 2 additional zones. I can play my TV, which uses a cable box through the main 5 speakers but not through the additional 2 zones. My goal is to have the sound from the TV/Cable box play simultaneously through all 9 speakers. Can someone help me figure this out?
