I pretty much have the sound systems up and running, the speakers are working great with some minor audio distortion (but that's probably because when I tested it, I didn't have the capacitors in). The microphone on the other hand is having some issues. I'm using the circuit from the demo board and the microphone to headphones object, but the audio I get back is very grainy. To get anything at all, I have to be within an inch of the mic. (could be because I yanked it out of an old phone). But overall, I get some audio.
