I know 5.1 with PC games isn't Dolby Digital or DTS, but I don't know what it is. I use a reciever hooked up to my sound card with digital coax. My soundcard has Dolby Digital Live. So I have some questions. 1. What is 5.1 surround sound with PC games? 2. Why aren't console games like that? 3. Does Dolby Digital Live downgrade the audio quality by converting it to a Dolby Digital signal that my reciever can recognize? 4. If a signal is just being converted from whatever it is to DD or DTS using DD Live and DTS connect, is either one actually better? Which raises my question on if Pro Logic II sounds better then Neo 6 (excluding Neo 6's 6.1 ability). 5. Without Dolby Digital Live can you play computer games in true surround sound using a reciever? 6. Could of swore once upon of time I got my reciever to just say PCM, is that what a raw 5.1 surround sound would sound like? Gets confusing figuring out whats doing what where and how and if it's actually working. Dolby Digital Live turns everything into a Dolby Digital signal but I can tell with my ears if it's stereo matrixed out or if it's a true 5.1 signal, so atleast I can sort that out no problem.
