click start , control panel , sound and audio devices.
click the audio tab.
does windows list the SigmaTel as default playback device ?
if not use the pull down menu and select it.
click apply and ok restart the pc.
would be a good idea to check to make sure your speakers are not at fault as well , and that the volume is turned up and not muted on the pc.
