Thanks that is useful. I wondered if it was an EE issue as I had problems with their hd voice codec on a different android handset. But I have just done a lot of testing and it definitely is only when on the normal internal speaker, which really makes me think it is a hardware fault.
Will phone CPW and get it swapped.
