I have the Latest Apple TV (3) & would like to know what is the correct setup to have sound come through my home theatre surround speakers. I had my optical digital audio cable connected to my Apple TV and from there connected to my home theatre receiver, but sound only comes from the TV speakers. I tried connecting the optical cable directly to the TV from my Apple TV audio port. Still, sound only comes through the TV speakers. I followed the Apple TV setup guide as instructed. Does anyone have any suggestions or tips?
