Bug Description

I think the Internal Microphone tegra-rt5640 does not work. I tried to record voice with the following apps but none of them worked:

- Voice Recorder
- RecordMyDesktop
- Kazam Screencaster

Even the sound check in the system settings failed.

Changed in ubuntu-nexus7:
status: New → Incomplete
