I think you'd need someone to figure out what/where is detecting the
combo jack is in use and whether it thinks an external mic is plugged in
or just blindly assumes one is plugged in.
I don't know what component is responsible for that detection so adding
a kernel task in case that's relevant...

Title:
Internal mic stops working when plugging in headphones
Status in linux package in Ubuntu:
Incomplete
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
I am currently running Quantal and when I plug headphones into my
headphone socket (which has an icon of a headset next to it, so I
presume it can take some kind of headset), the internal mic on my
laptop stops working. If I unplug the headphones the internal mic
works as normal.
I tried this with two different sets of headphones (one of which has a
mic, and the other I think has a mic too).
