From Amp / Port to Arc:
Can the Arc play music from analog devices connected to Sonos Amp or Sonos Port? I have a CD player and a turntable which I would like to listen to using the Arc. Is it possible to connect them to Port or Amp and stream the music to the Arc speakers or do I need to get an additional speakers?

Can input from the TV going to Arc be streamed to Amp or Port and played over the wired speaker connected to them?
