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). ** Attachment added: "14.04.3-alsa-info.logs" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1509921/+attachment/4520498/+files/14.04.3-alsa-info.logs ** Description changed: This is a desktop box, with following ports: front jack: a single headset combo jack rear jacks: mic, speaker, line-in An "Analog Input" consistently show up even there is nothing plugged, - but I'm not able to record via headset jack or rear mic jack, they all recorded with noises. + but I'm not able to record using headset via front combo jack or rear mic jack, they all recorded with noises. 00:01.1 Audio device [0403]: Advanced Micro Devices, Inc.
