I just built a new system and i'm currently using the onboard via audio sound card. The problem that I am having is that my sound quality isn't very good. The best way I can describe it is that the audio sounds kind of hollow. For example, video game gun fire sounds more like cap guns firing. I am only using a basic L/R speaker setup but they are the same speakers that I used with my old xp machine and I never had any problems there. This is my fist time using win 7 so I am hoping someone can point in the right direction as to how to try and improve my audio quality. Thanks.
