Creative Inspire 5300 5.1 Speakers need help

[jayboy86]

hi

i set up my pc with the Creative Inspire 5300 5.1 system and i have a sound blaster live 5.1

i did a sound test so each speaker calls out its name, so front left etc etc
they all say their names so i assumed it all works

but when im playing music nothing comes out of the center speaker, but i can hear the static like sound indicating the speaker is on

if when playing the music i pull the wire out of the pc a tiny bit the center speaker then plays the music, what confuses me is why i have to do this as when its fully plugged in, the test said center speaker and works.

i cant keep the wire a bit out as it goes on a off in im not apply some pressure, if i let go it will stop playing

im confused, any help would be great

thanks alot
