Thanks to all of you for resonding.

I have taken some compressed air and blew out any dust (especially off
the speaker) to no avail. I'm not too electronically inclined, but I
have been known to heat up a soldering iron on one or two occasions.
I'll check for loose connections tonight.

If you have any sort of small loudspeaker kicking around (like a PC
speaker), it would be worth substituting it or even just jumpering it
in parallel with the internal speaker to see if sounds any better.
