Not all Windows Media Player playback problems involve codecs. If your problem is codec-related, you'll probably receive a message like "A codec is required to play this file" or "Windows Media Player encountered an error." In this situation, follow the steps to learn more about the missing codecs. If it turns out that it's not a codec issue, see Troubleshoot audio problems in Windows Media Center for help with audio problems and general playback issues.
