I'm putting a pair of speakers in the ceiling in our new house in the living room to jam Sonos. The Connect Amp will be in my AV closet a couple rooms away. We will have a TV on the wall in the living room. Can I just connect the left and right RCA jacks on the back of my TV with an extender cable to the left and right RCA jacks on the Connect Amp pictured below? If so how would I tell Sonos to use the TV as a source to send sound to the in ceiling speakers and control the volume with the TV remote?
We will have an iPad mounted on the wall to control the Sonos music.
