Double check your Audio/Sound settings. Right-click on the speaker icon in your taskbar, and click on Adjust Audio Properties and check everything from there.
If all else fails, goto Device Manger, and check to see if there are any yellow exclamation marks next to the speaker icon. If not, then it could be corrupt drivers for the audio. What you will need to do then, is to simply delete the sound card information while in the Device Manager, then reboot. Windows will detect it and install the drivers for it.
