I guess I got it, after trying to fix it in every way I focused my attention on the sound card, because I read that probably that was the cause of the problem.
After trying a bit I reduced one notch the direct sound acceleration, and this worked for me.
You can find this setting in CONTROL PANEL\SOUND AND AUDIO DEVICES\ADVANCED (in the speaker settings) \PERFORMANCE
Hope this helps
P.S= I have a SB audigy
