External microphone cannot be detected

[Po-Hsu Lin]

CID: 201306-13687 Dell Latitude E6440

The external microphone cannot be detected when plugged in.
(Headphone is working, sound could be played through it).

Steps:
1. Install 12.04.3, boot to desktop.
2. Plug an external microphone in
3. Open "Sound Recorder", press the "Record sound" button and speak to the microphone
4. Playback

Expected results:
1. Sound could be recorded by the external microphone
2. In the "Input" tab of "Sound Settings", the device name would change from "Internal Microphone" to "Microphone" when it's plugged in.

Actual results:
The device name in the "input" tab of "Sound Settings" won't change at all.
The system still using the internal microphone for input device.

Verified with the latest mainline kernel, 3.12-trusty
There will be one more "Headset Microphone" device came up in the "Input" tab, and the external microphone could work if you manually select that device.
