Sooo many games say it on the box even though those games come on CDs. Example, Unreal Tournament 2004. It says it plainly on the CD version of the Box. I can understand it being Dolby Digital on the DVD version of the game, but the CD version? I know its possible, but: 1. theres no option for it in the sound menu. 2. I have a good soundcard with an Optical output which is conected to a Dolby Digital decoder, then to a creative 5.1 THX certified sound system. When I run 2004 through the optical output all i get is stereo sound, and the decoder doesnt recognize the Dolby Digital signal. I can get 5.1 though the sound card being directly conected to the creative sound system through the 3 (orange, green, black ) cables. God knows how those cables give us 5.1 but they do. My knowledge is based on my personal experiense with my home theater set up. I have a Digital Amp which offers DD and DTS. I conect my DVD player or X Box by a digital optical or coaxial cable. Result, Digital sound depending on what I choose from the DVD movie. Simple and makes sense right? SO how can a PC game offer it if theres no option for it, and no signal for it? The X box works because we can see the signal and the reciever recognises it as Dolby Digital, but with the PC, its a diferent story which i simply cant understand. Im I doing something wrong or are they?
