apache2 mod_deflate don't compress

Hi,

I use the turnkey lamp and have problems to enable compression by mode_deflate on a apache2 server. I don't have any idea why it is not working:

Modules are enabled:

# apache2ctl -M
Loaded Modules:
...
deflate_module (shared)
expires_module (shared)
filter_module (shared)
mime_module (shared)
...

000-default.conf:

 ...
 <Directory /var/www/>
     Options -Indexes +FollowSymLinks
     AllowOverride All
     Order allow,deny
     Allow from all
 </Directory>
 ...

.htaccess

 # Deflate Compression by MimeType
 <IfModule mod_deflate.c>
     AddOutputFilterByType DEFLATE text/plain
     AddOutputFilterByType DEFLATE text/html
     AddOutputFilterByType DEFLATE text/xml
     AddOutputFilterByType DEFLATE text/css
     AddOutputFilterByType DEFLATE text/javascript
     AddOutputFilterByType DEFLATE application/xml
     AddOutputFilterByType DEFLATE application/xhtml+xml
     AddOutputFilterByType DEFLATE application/javascript
     AddOutputFilterByType DEFLATE application/x-javascript
     AddOutputFilterByType DEFLATE application/x-font-woff
 </IfModule>

# Deflate Compression by FileType
<IfModule mod_deflate.c>
    <FilesMatch "\.(js|jpg|jpeg|gif|png|svg|css|eot|ttf|woff)$">
        ExpiresActive on
        ExpiresDefault "access plus 1 month"
        SetOutputFilter DEFLATE
    </FilesMatch>
</IfModule>

# turns cache on for 1 month
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType text/javascript "access plus 1 month"
    ExpiresByType application/javascript "access plus 1 month"
    ExpiresByType application/x-font-woff "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 month"
    ExpiresByType image/png "access plus 1 month"
    ExpiresByType image/svg+xml "access plus 1 month"
    ExpiresByType image/x-icon "access plus 1 month"</IfModule>

<IfModule mod_headers.c>
    <filesmatch "\\.(ico|jpe?g|png|gif|svg|swf|eot|ttf|woff)$">
        Header set Cache-Control "max-age=2592000, public"</filesmatch>
    <filesmatch "\\.(css)$">
        Header set Cache-Control "max-age=604800, public"</filesmatch>
    <filesmatch "\\.(js)$">
        Header set Cache-Control "max-age=604800, public"</filesmatch>
</IfModule>

PageSpeed Insights says: compression not active for svg-, css-, js- and html-files? Can someone help? Thanks!
