Enable windows audio services

Although the sound card and its drivers are installed correctly. some may receive the error message about no active mixer devices or some other messages when they tried to double-click on the Volume icon in the system tray of Windows XP.

Most people will assume the sound card itself is having difficulty or the drivers have no been installed, or maybe the system has been muted. However, when the computer starts or shuts down you hear the normal Windows sounds.
The main causes for this are,


check the controlpanel->sound&audio devices if it showed there are proper audio connections ok .

Then check the System Devices section of the Control Panel(controlpanel->sound&hardwaredevices->hardware->properties) to make sure the sound card was installed correctly and all drivers were installed. As you can see below, the sound card in this case the Realtek High Definition Audio card is installed and working properly.

3.It turns out the problem for this error lies in the Windows Audio Service, which usually starts automatically when the sound card is installed and working. However, in this case the service was turned off. Follow the instructions below to reactivate the Windows Audio service.
start->run->services.msc->windows audio
and check weather 'startup type' is 'automatic' &'service status' is 'started' then click ok

services.msc are disabled:-It may some times happen that services.msc (audio services) get disabled when u follow the process start->run->services.msc due to viruses.But u can get to them as stated below.
Open Computer Management, click Start, and then click Control Panel. Double-click Administrative Tools, and then double-click Computer Management.
Select Services and Applications from the console tree, and then select Services.
