title: Problem with notification sounds
body: <p>I am trying to test a notification. I have created an emulator with audio playback enabled. I am able to get the notification but I am not able to hear sound. What could be the problem? Are there any settings I am missing? </p>
  
  <pre><code>NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(ns);
          int icon = R.drawable.icon;
          CharSequence tickerText = "Hello";
          CharSequence contentTitle = "My notification";  // expanded message title
          CharSequence contentText = "Hello";      // expanded message text
  
          Intent notificationIntent = new Intent("ABC");
          PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
  
          long when = System.currentTimeMillis();
  
          Notification notification = new Notification(icon, tickerText, when);
  
          notification.defaults |= Notification.DEFAULT_SOUND;
  
          notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
  
  
          mNotificationManager.notify(HELLO_ID, notification);
  </code></pre>
  
  <p>When I saw logcat, I have the following stack trace. </p>
