Raspberry Pi and Microsoft LifeCam HD 3000 USB Webcam Built In Microphone

How to use a Microsoft LifeCam HD 3000 on a Raspberry Pi project. The webcam is Plug and Play, but the microphone does not work with Raspbian Jessie by default.

Goal: I wanted the default audio input to be the Built-In Webcam Mic, and the default sound output to be the normal 3.5mm jack on the Raspberry Pi.
