The Chrome hardware team designed this circuit and plug for functional testing;
however it has many other uses too. The Android audio team uses it to measure

via the Larsen effect (feedback loop).

To ensure that the output signal will not overload the microphone input,
we cut it down by about 20dB.
The resistor loads tell the microphone polarity switch that
