The Condemned Audio Surround Sound Help ?

[animepunk2103]

I have a surround sound hooked up to my ps3 with an optical cable. Im not very knowledgable about surround sounds ... but for some reason the first audio track in The Condemned Blu-ray wouldn't work. This is the first time this has happened to me so I didnt know if the condemned had some kind of audio format that my surround was not capable of. I had to hit the audio button and go to audio 2 for it to come over my surround sound. It still played in 5.1 as far as i could tell but i was just wondering what the deal is. I have a cheap surround sound and plan on upgrading to something new here in about a month. What do i need to get to have the best blu ray audio expierence. Some links to actual surround sounds would be helpful. I finally have a wonderful 1080p tv and now I want the best sound. Help me out people, please!
