I have a Denon AVRS530BT receiver and 4 in-ceiling, hard-wired speakers. I purchased a Sonos Soundbar/sub and two play 1's. I'd like to integrate the Sonos system with my existing speakers and receiver. The receiver plays through the hard-wired speakers fine, and I can stream fine through just the Sonos speakers, but I cannot get music or radio streamed through the Sonos app to play on the hard wired speakers. I've run an optical cable from tv to soundbar and from receiver (media player in) to a Sonos Connect. Already spent a full day trying to figure this out. I'd welcome any help. Thanks!
