How to play a sound file?

Question

I have found a solution on here to play a sound file in WPF which I extracted into a method and call this method in another method. But the when the PlaySound() is called the sound doesn't play. Does anyone have any insight as to why this is happening? Also the sound files are marked as content, but changing to type resource didn't remedy the problem either?

My method to play a sound:

private void PlaySound()
{
     Uri uri = new Uri(@"pack://application:,,,/Sounds/jabSound.wav");
     var player = new MediaPlayer();
     player.Open(uri);
     player.Play();
}

Then I call the method like this but its doesn't play the sound file, PlaySound();

Answer 1

You could also use a SoundPlayer

SoundPlayer player = new SoundPlayer(path);
player.Load();
player.Play();

Pretty self explanatory.

BONUS Here's how to have it loop through asynchronously.

bool soundFinished = true;

if (soundFinished)
{
    soundFinished = false;
    Task.Factory.StartNew(() => { player.PlaySync(); soundFinished = true; });
} 

Opens a task to play the sound, waits until the sound is finished, then knows it is finished and plays again.

It turns out that MediaPlayer does not play the music files in embedded resources, quote from Matthew MacDonald book: Pro WPF 4.5 in C#. Chapter 26:

You supply the location of your file as a URI. Unfortunately, this URI doesn’t use the application pack syntax, so it’s not possible to embed an audio file and play it using the MediaPlayer class. This limitation is because the MediaPlayer class is built on functionality that’s not native to WPF—instead, it’s provided by a distinct, unmanaged component of the Windows Media Player.

Therefore, try setting the local path to the your music file:

private void PlaySound()
{
    var uri = new Uri(@"your_local_path", UriKind.RelativeOrAbsolute);
    var player = new MediaPlayer();

    player.Open(uri);
    player.Play();
}
