I have some sound lags/stutter ingame. I would like to know if its normal in Hitman Absolution and if it can be fixed somehow or if it is a hardware problem.

Soundcard: Asus Xonar Essence STX
Graficcard: Nvidia Geforce gtx680 retail evga

I already deactivated my sound and graficcard and played hitman with my intel onboard grafic chip (intel cpu 3570k) and onboard sound chip (Motherboard MSI MPower Z77) but still the same problem.
