You need to install the drivers for your audio card or on-board sound. You may also have to install the drivers for your graphics card or on-board video. If audio and video are both on-board (not discrete cards) the drivers are on the CD that came with the motherboard. If you have discrete cards, you can either install the drivers that came on the CDs with the cards or get updated drivers at the vendors' websites - usually under a tab called Support.
