Ok so I have connected my home theater system, and cable box to my TV using HDMI cables. I was then told that by connecting a digital optical cable from the TV to the home theater system I will be able to play anything (such as a PS3 and my cable) on my TV in surround sound through the home theater system. I was looking at it though and it seems my TV has a Digital Optical Output, but my home theater system doesnt, it looks like it only has a Coaxial Input. I dont see a Coxial output on my TV either. Is there anyway for me to get my TV connected to my home theater system. Im looking for a way that isnt to costly, but also produces quality sound. Thanks for any help.
