I FIED MINE!!!
The raised plate looking thingy with tiny bumps around the flash seem to be
the cause of my issue.
I just took both thumbs and firmly but getly pressed on bothsides of the
flash plate thingy, and whala! Sound is loud as ever. Seems I reseated it.
Pop the battery cover on, sound stays loud.
Seems it can a tad loose when I dropped it a few weks back. D'oh!
