I lost sound on my PC after I tried to fast forward a video on facebook

[tarelle]

I have an HP windows 7 that I purchased several years ago. All was fine until I tried to fast forward a video on facebook. All of a sudden my sound disappeared on on programs regardless of whether chrome or IE, games, etc. I've done a lot of trouble shooting but still no sound. My sound is not muted.
