|Did you lose ALL sound or just sound from a player or sound from a site? None-the-less, you would still have to check all sound settings to see if one is muted or turned all the way down. if you have a speaker icon on your taskbar, r/click on open consol, make sure nothing muted, then will have to open you sound manager, again, make sure nothing muted. |
If all all settings are on, maybe try a system restore to the nearest day you know it was working.
