I just recently bought my PC which is a Gateway and also a sony home theater system. I connected both the receiver and computer together with optical wire. Well the problem is that when I listen to music, it works good. But when I try to watch a DVD movie and turn it to dolby surround sound. I can only hear the sound effect not the speech/talking of the actors. Yes, I've connected all of the wires from all 6 speakers that I have. If I set it to all speakers, it works good to watch..but I want to hear the surround sound just like in the movie theater. I am using CyberLink PowerDVD to play the DVDs and I also have the full version of it. If you guys know any better program to use then please tell me. I don't see what's wrong. Maybe I should buy a better sound card? But the sale man who I bought the computer from said that this card is good enough because it support optical pluggin. If anyone could help me I would be greatful because you would lose my head ache from solving this problem for weeks!! Thanks 😀
