Public bug reported:

CID: 201306-13687 Dell Latitude E6440

The internal microphone is not working.
And 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. Open "Sound Recorder", press the "Record sound" button and speak to the 
internal microphone
3. Playback
4. Plug a external microphone in, repeat 2, 3

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

Actual results:
1. Nothing but white noise could be recorded.
2. The device name in the "input" tab of "Sound Settings" won't change.

Verified with the latest mainline kernel, 3.12-trusty
There will be one more "Headphone" device came up in the "Input" tab, and the 
external microphone could work if you manually select that device.
However, the internal microphone still not working.
