Set Default ringtone, notification or alarm sound

Hi people! I am stuck on this. I try some ways to set defautl ringtone but none works for me :S any idea, I have this:

int tipo -> I send RingtoneManager.TYPE_ALARM (TYPE_RINGTONE OR ALARM)
String tipostring -> I send the name of folder (“ringtones”, “notifications”, “alarms”);

setSonido(RingtoneManager.TYPE_RINGTONE, "ringtones");

    public void setSonido(int tipo, String tipostring){
    	File newSoundFile = new File("/sdcard/media/", tipostring+".mp3");
    	Uri mUri = Uri.parse("android.resource://com.genaut.newapptest/raw/"+sonidoActual);
    	ContentResolver mCr = contexto.getContentResolver();
    	AssetFileDescriptor soundFile;
    	try {
    		soundFile= mCr.openAssetFileDescriptor(mUri, "r");
    	} catch (FileNotFoundException e) {

    	try {
    		byte[] readData = new byte[1024];
    		FileInputStream fis = soundFile.createInputStream();
    		FileOutputStream fos = new FileOutputStream(newSoundFile);
    		int i =;

    		while (i != -1) {
    			fos.write(readData, 0, i);
    			i =;

    	} catch (IOException io) {

    	ContentValues values = new ContentValues();
    	values.put(MediaStore.MediaColumns.DATA, newSoundFile.getAbsolutePath());
    	values.put(MediaStore.MediaColumns.TITLE, nombreActual);//Cambiar
    	values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mpeg3");
    	values.put(MediaStore.MediaColumns.SIZE, newSoundFile.length());
    	values.put(MediaStore.Audio.Media.ARTIST, R.string.app_name);
    	values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
    	values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
    	values.put(MediaStore.Audio.Media.IS_ALARM, true);
    	values.put(MediaStore.Audio.Media.IS_MUSIC, false);

    	Uri uri = MediaStore.Audio.Media.getContentUriForPath(newSoundFile.getAbsolutePath());
    	Uri newUri = mCr.insert(uri, values);

    	try {
    		RingtoneManager.setActualDefaultRingtoneUri(getApplicationContext(), tipo, newUri);
    	} catch (Throwable t) {
    		Log.d("ringtone", "catch exception");


This code adds the record to new sound on (Settings-> Audio profiles -> Ringtone calls ) But not set how default, and if i set it, not play the sound :S

Thanks a lot! and sorry my english
