How to Restart a Sound Driver
Windows 7 uses drivers to interface with the equipment installed to the computer. Without a working driver, a device can't receive instructions from the operating system. The Device Manager, accessible from Control Panel, enables users to control the drivers installed to the PC. If the audio output or input on the PC stops working, preventing you from giving a video presentation to potential customers or participating in a conference call with employees, the sound driver could be disabled. Restart the device in the Device Manager to restore function to the sound card.
1
Click "Start | Control Panel | Hardware and Sound | Device Manager," or click "Start," type "device manager" into the Search field and press "Enter."
2
Double-click "Sound, Video and Game Controllers." Right-click the sound driver and click "Enable" to restart the device.
3
Restart the computer, if prompted, to turn the sound card back on.
