how to play sound in sqlite

okay so i want to make an application .. but i have a problem to play sound in db

this my db

public void onCreate(SQLiteDatabase db) {
    String sql = "CREATE TABLE IF NOT EXISTS mad(_id INTEGER PRIMARY KEY AUTOINCREMENT, nama TEXT, keterangan TEXT, img BLOB, audio BLOB)";
    db.execSQL(sql);
    ContentValues values = new ContentValues();
    values.put("_id", "1");
    values.put("nama", "Mad Tabi'i");
    values.put("keterangan", ""); 
    values.put("img", R.drawable.tabi);
    values.put("audio",R.raw.sound_tabi);
    db.insert("mad", "_id", values);

and this is my activity

public void PlayAudioFile(String path, String fileName){   
            MediaPlayer mp = new MediaPlayer();

            try {
                cursor = db.rawQuery("SELECT * FROM mad ", null);
                adapter = new SimpleCursorAdapter(this, R.layout.isi, cursor,
                        new String[] { "audio", }, new int[] {
                                R.id.button1 });
                mp.setDataSource(path+"/"+fileName);
                mp.prepare();
                mp.start();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

this my dbparse

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.isi);

    Intent iIdentifikasi = getIntent();
    msg_im = iIdentifikasi.getIntExtra("dataIM", 0);
    String msg_nama = iIdentifikasi.getStringExtra("dataNama");
    String msg_keterangan = iIdentifikasi.getStringExtra("dataKeterangan");
    tv_nama = (TextView) findViewById(R.id.tvNama);
    tv_keterangan = (TextView) findViewById(R.id.tvKeterangan);
    Im = (ImageView) findViewById(R.id.iv_detail);
    button = (Button) findViewById(R.id.button1);
    Im.setImageResource(msg_im);
    tv_nama.setText(msg_nama);
    tv_keterangan.setText(msg_keterangan);
