I have the same bug on 14.04 LTS (Lenovo T430). When I plug the headphone the internal microphone starts to work incorrectly.
In the mixer I have two controls (1. for the headphones, 2. for internal mic) When the headphones are plugged in the mic starts to make some noises. Please let me know if you need anything from my end. Thanks for help.
