I have no idea how or why it happened. The video portion of the webcam works but not the microphone which used to work before.

Microphone works on Windows by the way, just stopped working on Ubuntu 12.10.

Webcam is a LifeCam VX-5500.

Here's some log files for now:

This maybe elementry, but... have you tried another USB port? More specificly, are you using a USB 3.0 port instead of 2.0? USB 3, from what I gather, is still a maturing technology and not sure if the kernel best supports it. –  hydroparadise Jan 3 '13 at 22:08
    
Yeap, tried all of them actually. Haha. –  Tek Jan 3 '13 at 22:13

Uninstalling all the kernels sudo apt-get purge linux-image-* and using a Live CD to run boot-repair fixed my issue.
