I know I've read something about this before but I can't remember what I could even check. I think this is a common problem.
Anyone know anything about it?

It's also possible that the connection from the speaker itself to the logic board might be faulty. My dad had a IIsi with an oxidized speaker connection-- this is a common problem with that model. If a sharp rap to the top of the case will occasionally restore sound, that might be the issue.

Take a look at the board and see if the capacitors have leaked all over. Bad capacitors in the audio circuit will kill sound, some machines like the LCIII will whistle while they die (unit will not turn on again without a recap).
