Hi all, Bit of background on my set-up: HDTV with 4 HDMI inputs (cable box, AppleTV, Bluray/surround sound, WiiU) and optical audio from TV to Bluray/surround sound unit for audio from whichever HDMI input is selected. My (self-created) problem is that I cannot AirPlay to AppleTV when TV is off or on a non-AppleTV HDMI input. I realized I need to take advantage of the optical audio out on AppleTV, bypass the TV, and go right for the Bluray/surround sound unit (confirmed by yanking optical audio from TV and inserting to AppleTV - AirPlay works with TV off). But, alas, there is only one optical audio port that is occupied by the TV (which is my priority). So, what are my options? I'm thinking either split the optical audio from the surround sound unit to go to TV and AppleTV OR pick up an optical audio to digital audio coax converter (or is it available as a single cable?). Also, would having the two audio outputs (HDMI and optical) pose a problem when watching, say Netflix, on the AppleTV? Any suggestions are greatly appreciated. Thanks!
