Jim,
Opps, sorry last post was bad.
470K resistor and cap do work.
Been to the circuit and done it.
It does work as advertised, so you do have a hardware problem.
Some times you have to use a value other than 470K because of the load you are
working into for your amplifier. As you have no audio, try a 47K or even a
4.7K.
The amplifier input you are trying to drive may be a lot lower impedance than
you expect. Watch out that you are not trying to drive a dynamic mic input
that has a DC voltage associated with it. That will put a charge on the cap and
cut the signal off also.
