    How are you connecting the 2.1 speakers?
    I assume they are "amplified speakers" that are AC powered, but laptops only usually have amplified (headphone) outputs, a mismatch in impedance.

    But the problem is possibly that the 2.1 speakers are grounded via the mains, while the laptop is isolated via the power supply 2 core lead. Therefore a large amount of mains hum/buzz could be generated. No real easy cure for that.
