Bug Description
CID: 201312-14381 Dell Latitude 3340
The Microphone mute on this system is not working
Steps:
1. Install 14.04 + update (3.13.0-27 #50)
2. Speak to the mic and record it, test the mic mute key to see if it works (fn+f4)
Expected results:
* Mic mute key should work, and the "Mute" option for input device should be ticked after you press the mic mute key
Actual result:
* Nothing happened
Debugging information:
From sudo showkey -k, keycode 248 press and release would be detected, when you press the mic mute combination key.
From xev, this event cannot be detected.
