my speakers are fucking up!?

[callen]

was just playing a little F1 challenge, and when the game starts i notice that it seems my speakers are echoing.....so i restart the computer, play some music in winamp and its still the same! it sounds like the sounds coming out of the speakers are far away, almost like being in a very big ballroom or hall....everything seems far away, and it sucks. i checked settings and i dont see nething different, i changed settings for winamp, to no avail.....does neone know whats up? i have cambridge soundwork creative 4.1
