The above happens if your instantianting multiple instances of the MediaPlayer.

You should read about the lifecycle of the media player and its different states

• Define one media player, at class variable scope for example
• Instantiate it in the Oncreate method and in the OnResume methods as required
• in your function to play your audio use the .reset method to get the media player to go into and idle state
• use the .setDataSource or equivalent to get it into an initialised state
• then .prepare for the prepared state
• then .start to play the audio
• .stop() etc to stop it
• when your finished use the .release function to release the audio resource.

Media Player is defined as a class scope variable and instantiated in the OnCreate() Method

    private void startPlayingAudio()
{
    try {

        Uri path1 = Uri.parse("android.resource://com.yourpackagehere./" + R.raw.beep);         
        mp.reset();  // reset to idle state
        mp.setDataSource(this, path1); // from idle to initialised state

        mp.prepare();

        mp.start();         
    } catch (Exception ioe) {
        Log.e(LOG_TAG, "Error playing the beep sound");
    }
}
