if you can get audio from the speaker at all, and if your voice comes through the PA speaker, then the audio chip is most likely not your problem.
to me it sounds like this radio has talkback installed, which is not a factory installed feature.
there might be wires coming loose from the PC board, or from the switch body itself.
it could also be that one of these wires is touching the metal case of the radio either at the point where the wires connect to the PC board or at the switch.
look for two wires soldered to the PC board near where the external speaker and PA speaker jacks are.
these two wires probably run to a switch of some kind.
check these first and if you dont have any luck, try flexing the radio a bit, and very gently pushing on the PC board to try and recreate the stresses of a radio mounted in a vehicle.
good luck,
LC
