a quick verification with 14.04.3 on stock image created live usb, headset microphone recording still not working, on both front combo jack and rear mic jack.
and a clarification, I was also using headset to test with mic jack, and it got a lot noise, but today I try to use a dedicated(stand alone) microphone on rear mic jack, recording works with both kernel(3.13, 3.19).
