How to Install Windows XP and 2000 Default Codecs Manually
When Windows XP and Windows 2000 are freshly installed from clean state, normally the default must have codecs to play sound in Windows will be installed for each installation. However, if Windows setup does not find or detect a sound card, these default Microsoft built-in codecs may not installed. When the sound card is added or the sound card driver is installed later on, some cheap low end sound card drivers do not detect the availability of these default codecs and install one if not exist, although most branded or high end sound card drivers such as those from Creative Labs will handle this scenario properly.

To check if your system affected by missing default Windows codecs, go to Control Panel -> Sound and Audio Controllers, then click on Hardware tab. Select the Audio Codecs entry and then click on Properties.
