Try installing the drivers.

 

This is the problem i dont know what drivers i need to instal.

 

Try rolling back or uninstalling your audio drivers

 

Go to start,run then type dxdiag
then go to the sound tab, on the sound page it shud tell you a name of your sound card. Once you have the name of your sound card try and download some drivers.
