D语言 bindings库 XAudio2 无法发音 ...

头文件 XAudio2.d 里 interface IXAudio2Voice 改为 extern(C++) interface IXAudio2Voice
不要继承自 COM 抽象基类 IUnknown 即可 (这帮为D DirectX 编写的程序员可能是粗心了 没注意到吧 ... 话说写完自己也不测试一下吗 ..-_-)

以及一下都要改 跟上面是一样的 ...
IXAudio2EngineCallback
IXAudio2VoiceCallback
以及一切继承至 IXAudio2Voice 的类 ...

附一个不成熟的测试 代码
