Windows Media Player error on startup

Hello,
When I try to play a song in windows media player I get this following error, ‘No sound driver is available for use’. I am getting this error only after the system update; do I need to update the drivers too? Before the update I think it was working fine. Am I guessing right? Please explain me where I went wrong. Your help is great. Thanks.
