I hear that.
Keeping in mind that nothing may be immediately visible, and your solder skills may or may not be up to the challenge, you can at least look into the problem.
Unplug the device and remove any batteries (yeah, obvious right? you'd be surprised), then open up the unit.
First, I'd take a look at the speaker wires where they connect at the speakers themselves. Depending on your machine there could be one large speaker or several, usually in pairs (stereo, go figure). These are usually among the last things to be soldered in during assembly, and done by hand rather than a machine like most of the main board. Then examine where the speaker wires attach to a circuit board. Again, these are usually hand-soldered.
If you have more than one circuit board in there, then look at the connecting wires or pins and see if there are any problems there. Use magnification and strong light if you have it.
After that, then I'd look at the solder connections on the circuit boards.
If you are going to resolder something, then you want to use solder-wick or at least a solder extractor to remove the old solder. If it's cracked, dull grey solder that doesn't want to melt, then you'll want to flush that garbage out with clean solder-- Sometimes I have to hold solder wick on one side of the joint and melt fresh solder in the other side until I get all the junk out (it helps that I have a microscope to see all this), but this is atypical. Once you have removed the old solder, then resolder your joint, but don't overdo it-- too much solder can be almost as bad as too little.
