I insalled windows 8.1 on my computer now my sound card does not work. I updated the drivers and nothing happened. I tried to revert back to the old drivers but that option is blanked out.When I go to the control panel the sound card shows up and it says it is working properly but I do not have sound.
No, the mute button is not checked.
