I recently purchased an Apple TV and have some questions about connection issues. I have a Sony Bravia 40" 1080p LCD HDTV model number KDL-40S5100, A Sony Blu-ray disc/DVD home theater system model number BDV E780W, and the Apple TV. My goal is to play the audio through my Sony home theater system surround sound. I feel as though I have tried every HDMI and optical audio connection, but still am unable to get the audio to play through the surround sound and the Apple TV screen to come up on my TV at the same time. I have two HDMI cables and two optical audio cables. Can someone please explain how to run the HDMI and optical audio cables from the Apple TV to the receiver and to the Sony Bravia TV? I have read a few things about needing an HDMI switch, but don't know if that is necessary. Thank you for your help in advance!
