Selecting "Analogue In" in Pulseaudio mixer is same as selecting "Microphone" - i.e. sounds recorded are always the Internal microphone, and not the microphone connected via the TRRS plug. When using OSX however, the TRRS microphone works correctly. Have tried booting Live CDs of 12.04, 13.04, and 14.04, and even tried upgrading kernel to 3.15, and problem persists.
