If the sound is not working and the sound device is active and enabled in device manager then it’s quite possible the “Windows Audio” Service is not running. To check, go to “Start” -> “All Programs” -> “Administrator Tools” and select “Services”. In the list of services, scroll down to “Windows Audio” and double click on it. The Startup type should be set to automatic and the service status should show started. If it is not started, press the “Start” button. On some slower machines that are overloaded with start up services and applications, it’s possible not all of the services will start in a timely manner such as the Windows Audio service. If the service continually does not start on boot up, look into disabling some of the start up programs or services.
