i updated my graphics cards driver and of course since something always has to go wrong, the sound doesnt come out of my tv anymore. so i looked it up and someone advised not updating that driver but i already had updated it and the rollback feature was not able to be pressed so i decided to just uninstall the driver (why not since it doesnt work anyway) and now i have no sound and no idea what to do next and i need help. i have an amd graphics card r9 380 4gb gaming graphics card. somebody save me plz.
