How to Restart a Sound Driverby Heather Bliss ; Updated September 28, 2017
Computer sound is an important part of any computer setup, especially those used for music or movies. When sound goes out, the problem can often have a simple solution, such as restarting the sound driver. Restarting a sound driver is easy to do, whether you just need to reboot the sound card driver, or whether your sound problem requires a full driver reinstall.
Restart the computer, which will automatically restart the sound driver if it is loading without any errors.
Restart the sound driver manually by disabling and re-enabling the sound card driver. Access your Windows control panel from the Start menu. Double-click the System icon.
From the System Properties window, click the Hardware tab. Select the Device Manager button. Press the plus (+) button next to the Sound, video and game controllers menu, right-click the driver you wish to restart and uninstall the driver.
Reinstall the driver using the driver disc from your sound card.
