The thing is that I use a USB headset, but when I unplug it and even go to audio options to make my Altec speakers my sound device, the sound is rather corrupt when played through the speakers, while the headset is always fine. Please have recommended that I upgrade my drivers, but I don't know which one to get, because there are just so many. I have SigmaTel audio CODEC, and am running a PC with Windows XP MCE.
