Public bug reported:
CID: 201306-10387 Dell Latitude E6440
The internal microphone is working on this system, but it seems that the
internal microphone works during the pre-install certificate stage.
Step:
1. Install 12.04.3 and boot to desktop
2. Open "Sound Settings", switch to "Input" tab, speak to the internal
microphone and observe the input level indicator.
3. Open "Sound Recorder" to record sound
Expected results:
1. The input level indicator should change when you speak.
2. Sound could be recorded
Actual results:
1. Input level indicator won't change
2. Nothing but white noise could be recorded
Verified with the latest mainline kernel, 3.12 trusty, this issue still
exist.
