FM Radio shield problems (si4735)

Hey guys,

looking for a little help with the si4735 FM radio shield from sparkfun: I bought this about a year and a half ago, but put the project on the back burner until now. Sparkfun no longer make this product so I realise its going to be a little hard to get help, but its worth a try.....

I am using an arduino uno, the shield, the example sketch from the library that ships with it (at the above link) and a standard pair of headphones, but I'm unable to get any kind of audio out.... not even static.

I have read that there are several problems with this product and that there are a few modifications you can do to get around these problems, but I've also read that you should at least be able to tune in some stations and get some sound out of it using the basic setup.

Anybody have any ideas? I'm not even sure how to start debugging this .
