Question: Anyone suffering speaker failure on their 8830 (Sprint)?

I recently purchased a refurbished 8330 & it worked fine... for a day. Suddenly,
the speaker went out. It vibrates & I can hear sound through wired headsets (I haven't
tried blue-tooth). I did a battery pull, there are no applications on the phone except
those that came pre-installed. Any help?
