Only getting half the sound through surround speakers

[aaronpawlak]

Hello,


I have Logitech x-540 speakers, and an external USB soundcard for my laptop.
I'm using windows 7 home premium.
For some reason the sound is only playing through the green 'front' speakers cable, I still get bass through the sub but half the speakers don't work and I'm only getting half of the sound- there are parts missing from songs. Its incredibly annoying, it worked ok before so I cant figure out whats gone wrong. Anyone got any ideas?


Please help.


I didn't find the right solution from the Internet.
