Have you tried to update drivers? Type Device in search on Start and choose
Drvice Manager. Choose your audio device, right click and choose Properties
then the driver tab and choose Update Driver.
If the above finds no new drivers go to the computer manufacturer's web site
and download the drivers from there.
