playing audio from Application in blackberry?

I want to play audio from my application. the following code is used

 try{
     Player p = javax.microedition.media.Manager.c开发者_运维知识库reatePlayer("file:///store/home/user/recording.amr");
     p.realize();

     VolumeControl volume = (VolumeControl) p.getControl("VolumeControl");
     volume.setLevel(30);

      p.prefetch();
      p.start();
    }catch(MediaException me)
    {
        Dialog.alert(me.toString());
    } 
    catch(IOException ioe) 
    {
        Dialog.alert(ioe.toString());
    }

then i get an exception net.rim.device.internal.media.rimmediaexception : Media unloded while initializing

Any idea about this exception?
