I just recently ran updates on my Ubuntu 12.04LTS and noticed that there were updates to PulseAudio. Just my luck and I have discovered an issue with no sound via only headphones. I have verified that I have sound via PC Speakers but when using no headphones no sound at all.

I have also verified that headphones are ok, I have tested them on multiple devices and I'm able to hear sound just fine.

Something must have changed within pulse audio to break sound via headphones, how can I troubleshoot this?

Headphone working perfectly fine until I updated Ubuntu. What information can I provide to help resolve the issue.

Please help!!!
