Finally fixed it, thank you fellas for your help.

Updating to Windows 10 made it work, video files now have sound when playing with media players.

A big thank you to Optimus as his directions worked...I uninstalled the updating files with windows 7 then attempted to update to windows 10, Thank you mate...you are a genius, a vital player here at SBR
