By default, Windows Server 2012 doesn't have the audio service enabled, likely because it won't be needed on many servers, which may not even have speakers attached to them. You can enable the service by several different methods. You can run
services.mscand start the
Windows Audioservice. You can also change the startup type from manual to automatic to have the service start automatically when the system boots. Another method for enabling the audio service is to right-click on the speaker icon in the notification area at the lower, right-hand corner of the screen and choose Playback devices. You will then see a message asking whether you wish to enable the audio service. If you choose "Yes", the service will be enabled and the startup type will be changed to automatic so the service will start whenever Windows loads.
