Filter site URL

Hi,

I can’t find a way to have a dynamic link to my homepage. I’m using the get_site_url() function but it always return my english URL.

* Running Polylang 1.1.6 on WP 3.7
* Permalinks structure is /%postname%/
* Using lenguage code in URLs (example.com/es/somepage)

When I’m in the spanish version, I expected that get_site_url() would return example.com/es, instead it returns example.com (which is the default language). Is there any way around this?
