Audio Device is Disabled

Recently we've had a problem with some computers not producing sound. When running the troubleshooter that Microsoft provides its tells you that an "Audio Device is Disabled." But not how to re-enable it. So this is how.

First Option

First, right click on the speaker icon in the notification area (which probably has a small red cross on it) and choose 'playback devices'

Now you should see a speaker icon in the middle of the box that has just opened. Under this right click and one of the options you will be presented with is to show disabled devices. Click this and if any device is disabled, it should appear. You may also have to check the Recording tab at the top. You can then right lick on this device and select 'enable'.

Second Option

If this doesn't work, or it keeps crashing when you try it, then it may be a permissions problem and you should try this.

Click start and type in cmd in the search area. Once found right click on the program and choose 'run as administrator'. The command prompt will now open and you should type this in.

net localgroup Administrators /add networkservice
Press Enter
net localgroup Administrators /add localservice
Press Enter and then restart your computer.

This should have fixed the problem for you.
