Sony Ericsson W595- call speakers not functioning

Great phone, only problem is that the speakers have broken when you try and answer a call.You can not hear anything unless you turn the phone back to front!! so frustrating.
I have owned this phone for 2 years and have not had a days issue with it, so I am disappointed that it has now chosen to break.
The walk man speakers work great and I love having this function, I have put so much music on the phone.
I can text, take pics, listen to music, just not make calls.
So sadly I will have to look at a new phone.

Has anyone else had this issue, I would love to know if there is an answer without buying a new phone.......

Thanks.
