Apps mediaplayer interruptted in repeat

[desatir7316]

hi there
on MotionEvent.ACTION_MOVE i want to play a shot sound repeatedly
but after a moment it will be silent and i solved it by followwing code:

 mPlayer = MediaPlayer.create(this, R.raw.tirbar8);
 mPlayer.start();
mPlayer.setOnCompletionListener(new OnCompletionListener() {
                public void onCompletion(MediaPlayer mp) {
                    mp.release();
                }
            });

now i have a interrupt in my sound
how to solve it?
