Remove Standard Enfold Logo

Hi,

i’d like to remove the standard Enfold Logo and replace it with the title of the Website.
I tried several codes but nothing works.

If i add this code ….

add_filter(‘avf_logo_subtext’, ‘kriesi_logo_addition’);
function kriesi_logo_addition($sub)
{
$sub .= “<span class=’logo-title’>”;
$sub .= get_bloginfo( ‘name’, ‘display’ );
$sub .= “</span>”;
return $sub;
}
…. the site titel shows but the Enfold Logo remains.
What can I do to remove it without removing the site titel too
Thank you for your help
Regards
Sabine
