- 1996 DirectSound
- 1998 WaveOut
- 1999 年 ASIO
- 1999 Windows Media Player ActiveX 控件?
- 2005 WASAPI(由 XAudio2 使用 - 正如@Han 所建议的那样)
- 2007 XAudio2
- 1991 WinMM.dll/mmsys.dll PlaySound
- 1995 MCIWnd (as suggested by @casablanca)
- 1996 DirectSound
- 1998 WaveOut
- 1999 ASIO
- 1999 Windows Media Player ActiveX control?
- 2005 WASAPI (which is used by XAudio2 - as suggested by @Han)

推荐答案
这真的取决于你想做什么.对于大多数常见情况，我发现 MCIWnd 功能运行良好:它们非常易于使用，并且可以播放安装了编解码器的任何格式.
Really depends on what you want to do. For most common scenarios, I've found that the MCIWnd functions work well: they're really easy to use and can play any format for which a codec is installed.
DirectSound 使用起来有些困难，但可以让您更好地控制输出；它可以让您添加特殊效果和模拟 3D 定位.
DirectSound is somewhat more difficult to use but gives you much more control over the output; it lets you add special effects and simulate 3D positioning.
waveOut 函数是您可以获得的最低级别的 API，它们是一把双刃剑:您可以准确控制输出到扬声器的内容，但它们只接受原始数据波形数据，这意味着您负责输入数据的所有解码和后处理.PlaySound提供了一个很好的包装.
The waveOut functions are the lowest level API you can get to and they are a kind of double-edged sword: you get to control exactly what goes out to the speakers, but they accept only raw waveform data, which means you are responsible for all decoding and post-processing of input data. PlaySound essentially provides a nice wrapper around this.
