Bro how do you set up a 2.1 speakers(logitech z623) on windows 7?? theres no 2.1 option and im using the stock sound card on my MSI Big bang xpower motherboard. Using realtek HD driver. Sound test on my headset is normal but when i switch it to my 2.1 speakers the left speaker got the bass sound and right speaker got its normal sound on test. Got the wire plugged right to the front speakers out (green one)
