这是文档中的错误.AudioEngine 实际上在 Microsoft.Xna.Framework.Xact 程序集中.添加对此的引用，一切都应该按预期工作.

This is an error in the documentation. AudioEngine is actually in the Microsoft.Xna.Framework.Xact assembly. Add a reference to that, and everything should work as expected.

请注意，XACT 在 Windows Phone 7 上不可用(这就是它位于单独程序集中的原因).如果您打算稍后使用移动设备，请改用 SoundEffect.

Note that XACT is not available on Windows Phone 7 (this is why it is in a separate assembly). If you plan to go mobile later, use SoundEffect instead.
