wp8 Soundeffect can't stop - windows-phone-7

Question

I use soundeffect to play sound from byte array and all things go alright, but i cant stop playing the sound because no method called stop() in Soundeffect, how i can stop it ?
The code:
private void playFile(byte[] file)
{
try
{
if (file == null || file.Length == 0) return;
SoundEffect se = new SoundEffect(file, microphone.SampleRate, AudioChannels.Mono);
SoundEffect.MasterVolume = 0.7f;
if (stop != 1)
{
FrameworkDispatcher.Update();
se.Play();
}
else
{
//Here should stop, how !
}
}
catch (Exception ee)
{
MessageBox.Show(ee.Message);
}
}

Answer 1

Have you tried calling .Dispose() on your SoundEffect object? According to the documentation,
When a SoundEffect object is destroyed, all SoundEffectInstance
objects previously created by that SoundEffect will stop playing and
become invalid.
Additionally, Microsoft recommends using MediaElement instead, unless you're developing with XNA Game Studio 4.0. So if that applies to you, you may want to consider using MediaElement which does have Play, Pause, and Stop functions.

Answer 2

try using SoundEffectInstance
Sound effect instance
Here's a link to the solution
Sound Effect Instance
More over SoundEffectInstance implements IDisposeable so it will have a dispose() method as well as stop() for the sound effect .

Answer 3

Create a variable for SoundEffectInstance as shown below
SoundEffectInstance soundEffectInstance;
then create an instance of your soundEffect after loading the file..
soundEffectInstance = se.CreateInstance();
after that use this soundEffectInstance to Stop, Play or Pause where ever you want in particular scope.
soundEffectInstance.Play();
Note that SoundEffect is used for fire and forget type instances, if you want to control any particular instance of a SoundEffect you will need to use SoundEffectInstance.
I agree with Benoit Catherinet. If you are trying to stop a particular sound on some event then you must place the stoping code in that event method and for that your SoundEffect instance must be global and not local.
We can better help you if you can explain about what you are trying to achieve.
