I am just about to set up a new Plasma and a Yamaha 1800 receiver which has 4 HDMI inputs. I will also add an Apple TV, DVD player and an S3. My wish is to use HDMI for sound and picture for ease of use. I was just wondering though if I will lose the ability to play music on my stereo while watching TV. Assume the music is coming from a Sonos digital music system which will be hooked up to an input on the Yamaha. Can I select input on the Yamaha which plays the tv but override the tv sound by selecting the Sonos input? I am hoping the answer is that the S3 has to have a separate TV input but I am believing that this may be the case. Any suggestions?? Thanks.
