I can not get sound with notification
<p>I can get text with notification; but when notification is got, I want to hear a sound.</p>

<p>The android code:</p>

<pre><code>private static void generateNotification(Context context, String message) {

    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(R.drawable.ic_launcher,
            message, when);

    notification.defaults|= Notification.DEFAULT_SOUND;
    String title = context.getString(R.string.app_name);
    Intent notificationIntent = new Intent(context,
            GCM.class);
    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);


}
</code></pre>
