dude. seriously, how can you get 5.1 output from your laptop when your laptop doesn't have audio ports for 5.1 setup?
Your laptop has this:
1 x audio - line-in/microphone - mini-phone 3.5 mm
1 x audio - line-out/headphones - mini-phone stereo 3.5 mm
1 x audio - line-in - mini-phone 3.5 mm
For 5.1 channel setup you need to have 3 audio out ports (apart from one line in and one microphone port).
In short, your laptop doesn't support surround sound. Get a Express card based sound card.
Didn't you check before buying laptop/speakers for 5.1 channel support?
