I have a mate who had just formatted his comp and reinstalled his o/s. Since he has done this the sound that it produces is so crackly and broken taht you cant bear to listen to it, it seems to happen when you open up aplications or try to make the machine do anything. Is this a driver issue? It comes up as a sound max card when windows detects it but in the manual it states that it is a Via AC'97 card!?!? Any thoughts would be appreciated as always!
