I want to play sound from multiple sources on my Sonos speakers using the Sonos Port. I have a JVC RX-702B receiver (link to manual: http://resources.jvc.com/Resources/00/00/90/LVT1437-007A.pdf). Would it work to connect the Port's line-in to the receiver's DVR out/record? Will the digital connection from the Port to the receiver's digital in 1 (DVR/DVD) still work to stream from the Port to my non-Sonos speakers? It's there a better way?
