Hello, how do I sort the sitewide listing of all galleries by alphabetical order?

I have tried in functions.php but it does not work:

function buddydev_modify_media_order( $args ) {

$args['orderby'] = 'title';

return $args;
}
add_filter( 'mpp_main_media_query_args', 'buddydev_modify_media_order' );
