Okay so this is what I have so far:
Vdd connected to 3.3V, ground connected to GND pin next to MIC pin, and output connected to MIC pin with 10uF capacitor (not 25uF I was mistaken).
The code I'm using is the PassThroughStereo example (pasted below), and all I hear is a buzzing sound coming through the headphones.
I've tried uploading pictures but everytime it says upload failed.
/*
* A simple hardware test which receives audio from the audio shield
* Line-In pins and send it to the Line-Out pins and headphone jack.

* This example code is in the public domain.
