How to: Stop or Pause a Sound

This example demonstrates how to initialize the audio engine, load a sound bank and wave bank, and play, pause, resume, or stop a sound (called a cue). This example builds off a simpler example, How to: Play a Sound.

This example assumes you have already built an XACT sound bank and wave bank. To learn how to do this, see How to: Add a Sound File to Your Game Using XACT.

To stop or pause a sound

  1. Create an AudioEngine, WaveBank, and SoundBank at game start.
  2. During game update, call the Update method of the AudioEngine to allow the audio engine to process audio data.
  3. Retrieve a cue you wish to play by calling SoundBank.GetCue. Store the cue value that is returned.
  4. Once you have played the cue by calling Cue.Play, you may choose to pause the cue by calling Cue.Pause, or stop the cue entirely by calling Cue.Stop.
  5. If you wish to resume a paused cue, you can simply call Cue.Resume.
  6. If you wish to play a stopped cue, you must reacquire the cue by calling SoundBank.GetCue.
