Compass written with Assetic on Symfony 2

This is my first time I used Symfony, so I don’t know if I’m all confused or what, but I can’t get the compass to write while working on my project, apparently.

This is what I have on my scss files:

@import "compass";
@import "compass/css3";
@import "compass/utilities/sprites";
@import "icons/*.png";
@include all-icons-sprites;

And I do not see any errors when compiling sass, but the icons are not found anywhere, and the generated css is something like:

 .icons-sprite, .icons-icon01, .icons-icon02 {
     background: url("/images/icons-sf92f9256db.png") no-repeat scroll 0 0 rgba(0, 0, 0, 0);
 }

In my config.yml file, I have the following:

assetic:
    debug:          "%kernel.debug%"
    use_controller: false
    filters:
        cssrewrite: ~
        sass: ~
        compass: 
            bin: '/usr/bin/compass'
            apply_to: "\.scss$"
            http_path: /
            images_dir: %kernel.root_dir%/../src/Es/DolceVitaBundle/Resources/assets/images
            generated_images_path: %kernel.root_dir%/../web/images
            http_generated_images_path: /images

parameters:
    assetic.filter.compass.images_dir: %kernel.root_dir%/../src/Es/DolceVitaBundle/Resources/assets/images
    assetic.filter.compass.http_path:  /images

And the folder of my icons (with the png source files that I want to use for the sprite) is in / Myprojectfolder / src / src / Es / DolceVitaBundle / Resources / assets / images

The folder in the / Myprojectfolder / src / web / images folder is empty

EDIT:

Additional info: I made app / console assetic: dump --watch and css files were created perfectly

And my stylesheets are added as follows:

{% stylesheets output='css/*.css' filter="compass" 
    "@EsDolceVitaBundle/Resources/assets/scss/style.scss"
%}
    <link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
