Hello I'm new here and I'm not a very techy person but I try! Anyways, I recently bought an Apple TV and I connected to my HDTV through an HDMI cable. However, I want the sound to come out through my Philips home theater. I currently have my TV connected to my Comcast HDcable box with an HDMI cable, and the cable box is connected to my home theater by using the red,yellow and white cables so the sound comes out from my home theater when I watch cable TV. I want the sound to come out from my home theater when I use the Apple TV as well but I don't know how since the AppleTV only has an HDMI port and an optical audio port. I know that there isn't a connection between the Apple TV and the home theater so that's why the sound is only coming from the TV speakers but how do I solve this situation. Do I have to buy anything? My home theater doesn't have an optical audio port so I don't know how to connect these 2 so that when I watch TV or AppleTV the sound can come out from the home theater. Thanks so much in advance! P.S. I apologize if this has already been answered, if it has please send me the link.
