In my JumbledWords game app, I am providing options to Turn On and Turn Off the sounds. The problem is that I am not able to do that. I have written the code for it but it 's not working. 

**SplashScreen.java**

```
RadioButton rbSoundOn, rbSoundOff;
JumbledWords jw = new JumbledWords();
@Override
public void onCreate(Bundle bundle)
{
    super.onCreate(bundle);

    //set the full screen view of the activity
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.splash_screen);

    rbSoundOn =  (RadioButton)findViewById(R.id.optSoundOn);
    rbSoundOff =  (RadioButton)findViewById(R.id.optSoundOff);

    if(rbSoundOn.isChecked() == true)
    {
        jw.setSoundOn(true);
    }
    else
    {
        jw.setSoundOn(false);
    }}

```

**JumbledWords.java**

```
static boolean soundOn;
public void setSoundOn(boolean soundOn)
{
    this.soundOn = soundOn;
}

public boolean isSoundOn()
{
    return soundOn; 
}

public void checkWord()
{
    if(abcd.equalsIgnoreCase(etGuessedWord.getText().toString()))
    {
        WordLibrary.setMyInt(WordLibrary.getMyInt() + 10);
        tvScore.setText(String.valueOf(WordLibrary.getMyInt()));
        if(soundOn == true)
        {
         mp = MediaPlayer.create(this, R.raw.clap);
         mp.start();

         mp.setOnCompletionListener(new OnCompletionListener(){

            @Override
            public void onCompletion(MediaPlayer arg0) {
                // TODO Auto-generated method stub
                mp.release();
            }

         });
        }
    }
    else
    {
        if(soundOn == true)
        {
         mp = MediaPlayer.create(this, R.raw.oop);
         mp.start();

         mp.setOnCompletionListener(new OnCompletionListener(){

                @Override
                public void onCompletion(MediaPlayer arg0) {
                    // TODO Auto-generated method stub
                    mp.release();
                }

             });
        }

    }
}

```

My problem is that if I use the Turn Off option, my sound plays, which must not happen in this case. Please help me.
