Comment 0 for bug 1359803

I'm using Ubuntu 14.10 on my Asus 1015E that only has a combo audio port which accepts smartphone type "headsets" (3.5mm TRRS headphones with mic on the same wire).

Ubuntu does not deactivate the built-in mic when I connect my headset. It doesn't even use the headset mic and instead keeps picking up audio signal from the integrated microphone (that's on my laptop bezel).
