Steve,
My first guess is that the IDer has a low-impedance output, and is
connected at a high-impedance point in the audio chain. Just try lifting
the IDer's audio lead, to see if the repeated audio level comes back up.
If so, you might be able to correct the problem by putting a high-value
resistor in series with the IDer output.
My second guess is that the point where your IDer is connected may have a
DC voltage on it as bias for a following stage, but the IDer is not
AC-coupled. The IDer output may be DC coupled and is either upsetting the
bias, or is injecting a voltage that is charging a coupling capacitor and
cutting off an amplifier.
