Apparatus standard notification ringtone

Question

In my application I have in the settings an option for the user to select the sound that will run when receiving notification.

Then I open one AlertDialog and list the standard ringtone of the device itself:

Uri defaultRingtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone defaultRingtone = RingtoneManager.getRingtone(context, defaultRingtoneUri);

I get the title and location with:

//Titulo
defaultRingtone.getTitle(context)
// Path
defaultRingtoneUri.getPath()

And the other notifications thus obtained:

RingtoneManager manager = new RingtoneManager(context);
manager.setType(RingtoneManager.TYPE_NOTIFICATION);

Cursor cursor = manager.getCursor();

The title and location, after doing the loop, get with:

// Título
cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX)
// Path
cursor.getString(RingtoneManager.URI_COLUMN_INDEX) + "/" + cursor.getString(RingtoneManager.ID_COLUMN_INDEX)

Problem

What happens is that the first name of the notification (which I get by the first code), on my device the title shows Standard ringtone (Tejat), which is true, but when I go to play the sound is a different one and not the Tejat.

And when I play Tejat obtained by RigntoneManager, is the right sound.

Standard ringtone (Tejat): /system/notification_sound
Tejat: content://media/Internal/audio/media/7

Question

What happens so the default ringtone isn’t really right? How to resolve this?
