good point Doc. Are your speakers plugged into the right jack in the sound card?
volume control turned up? might sound silly, but happens. Also is your sound card listed under "other devices" in device manager. If this is a new install sometimes that happens. You might also go into safe mode, press f8 when booting, and look under device manager. See if the card is listed correctly or multiple times. Just some things to check.
