There are many ways of playing sounds on Windows. Which are the differences, advantages and disavantages of each method?

I know there are at least 5 methods:

  1. 1991 WinMM.dll/mmsys.dll PlaySound
  2. 1995 MCIWnd (as suggested by @casablanca)
  3. 1996 DirectSound
  4. 1998 WaveOut
  5. 1999 ASIO
  6. 1999 Windows Media Player ActiveX control?
  7. 2005 WASAPI (which is used by XAudio2 – as suggested by @Han)
  8. 2007 XAudio2

    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 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.

    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.
