Sure, you can hear sounds coming from all speakers but they\'re not surround. You\'re basically getting stereo sounds from all the speakers. Just because you getting sounds from all speaker, it does not mean that it\'s surround sound if you know i mean.
I use a computer equipped with sblive and dts 25000 speakers from cambrige. When i play bg2 with eax supports, it sounds awesome, when you move from one spot to another end of another spot, sound pans around the speakers, that\'s surround soud, in your case, when you play ps2 games, you\'re hear the same sound from all speakers. Well, like i said, eventually ps2 will have some games with surround support but it will be a hard task to do for ps2. For sblive, developers have to do is encode the eax emulation into the game and use sblive card to produce the surround sound. Ps2 does not have an dedicated 3d sound card the gaming part, but eventually they will some how figure it out
