MediaMonkey 依赖 Windows Media 组件来读取和播放 Windows Media 格式（WMA、WMV、ASF 等）以及 MP3 文件。因此，如果 Windows Media Player 无法播放 Windows Media 格式的文件，MediaMonkey 也无法播放。如果出现以下情况，可能会出现此类问题：
- 文件已损坏
- 文件受数字版权管理 (DRM) 保护
- Windows Media 组件未正确安装
- 你运行的是 Windows 10：http://www.mediamonkey.com/support/index.php?/Knowledgebase/Article/View/245/0/wma-encoding-fails-on-windows-10
1. 当特定文件损坏时，可以使用 asfbin 等工具进行修复：
http://www.radioactivepages.com/asfbin.aspx
使用该页面处理有问题的 wma 文件后，重命名生成的文件，然后在 MediaMonkey 中播放。
2. 如果某些 WMA 文件仍然无法播放、转换和刻录，并且/或者您收到错误“…某些曲目受数字版权管理保护…”，那么这可能是由于这些曲目受数字版权管理 (DRM) 保护，而您无权播放它们，这些权利可能已过期，或者 DRM 证书存在问题。请在线查找解决方案，以获取 DRMed WMA 文件提供商的系统证书。
3. 如果 Windows Media 组件缺失或出现故障，则所有 Windows Media 文件都将无法播放，尽管其他音频格式可以播放。这将导致：
o 没有声音，音量分析失败
o 同步失败、转换失败、刻录失败
o 标签更新失败（仅限 WMA）
o 关于无法解码 WMA 文件的错误消息
如果您安装了 Windows 'N'，而其中不包含播放所需的编解码器，则可能会发生这种情况。要解决此问题，您需要安装缺少的编解码器。
如果已安装 Windows Media 组件，则这些问题可能是由过时或损坏的 Windows Media 驱动程序引起的。解决此问题的方法如下：
1. 在某些情况下，只需重新启动机器，问题就会消失。
2. 如果重启不起作用，那么您可以尝试：
a) （重新）安装编解码器

b）（重新）安装 Windows Media Player，以确保安装了最新的编解码器

3. 要完全刷新 Windows Media Components（这也能解决 WMA 标记问题），请尝试：

MediaMonkey relies on Windows Media components to read and play Windows Media formats (WMA, WMV, ASF, …) as well as MP3 files. Thus, if Windows Media Player can’t play a file in a Windows Media format, MediaMonkey won’t be able to either. Such issues can arise if:
- a file is corrupted
- a file is protected by digital rights management (DRM)
- the Windows Media Components aren’t installed correctly
- you’re running Windows 10: http://www.mediamonkey.com/support/index.php?/Knowledgebase/Article/View/245/0/wma-encoding-fails-on-windows-10
1. In the case of file corruption of a specific file, a tool such as asfbin can be used to fix it:
http://www.radioactivepages.com/asfbin.aspx
After using the page to process the wma file in question, rename the resulting file and then play it in MediaMonkey.
2. If playback, conversion, and burning failures still occur with certain WMA files and/or you receive an error that ‘…Some of the tracks are protected by Digital Rights Management…’ then it is probably due to to the fact that the tracks are protected by Digital Rights Management (DRM) and you do not have rights to play them, the rights may have expired, or there is a problem with the DRM certificates. Check online for solutions to aquiring these certificates for your system for the provider of your DRMed WMA files.
3. In cases where there are missing or faulty Windows Media components, all Windows Media files will fail even though other audio formats may work. This will result in:
o no sound, volume analysis failures
o sync failures, conversion failures, burn failures
o failed tag updates (WMA only)
o an error message regarding the inability to decode WMA files
This can occur if you have Windows ‘N’ installed, which doesn’t include codecs needed for playback. To resolve, you’ll need to install the missing codecs.
If Windows Media Components have already been installed, these issues can be cause by outdated or corrupted Windows Media Drivers. To resolve this:
1. In some cases simply reboot your machine and the problem will disappear.
2. If reboot doesn’t work, then you can try:
a) (re)install codecs from
https://www.microsoft.com/en-us/download/details.aspx?id=507
b) (re)install Windows Media Player to ensure that latest codecs are installed

3. For a complete refresh of Windows Media Components (this will also resolve WMA Tagging problems), try:

Applies to: MMW4, MMW5+
