Bug Description
Microphone connected via TRRS plug on Macbook Air 5,1 is not recognised. 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.

this happens on the MacBook 6,1 (late 2009) as well. It has the same Cirrus CS4206.
I just tested the most recent alsa-daily which builds for wily/amd64 without effect. Internal Speakers, Internal Mic, Headphones all work - TRRS mic doesn't work (Mac OS X supports exactly this Headset device out of the box).
I'm using 15.10 GNOME Ubuntu. In sound settings I can only activate the internal mic and don't even see any external (as with output where the label of the output device automatically changes if the headset is connected).
