Prototype no sound fix on xp professional

[uka]

I have instaled game Prototype and there is no sound while playing. I read on one page that i have to : " Set the default format to 24-bits, 48000Hz or less (if it doesn't work with 48000Hz, try 24 bits, 44100Hz) " i have windows xp professional sp3 and i can't find that option... My computer is very good and i can properly run every game...I think that this option doesn't exist, so if somebody can help me i would appriciate
thanks for help

That option should be in your sound and audio devices in the control panel. You may have to go into the advanced for your audio playback device settings to find it.
