Public bug reported:

CID: 201306-13836 HP Pavilion 15

The mute button itself works fine.
There is a small LED on the mute button, but the LED seems not working

Steps:
1. Install 12.04.3 + update (3.8.0-33) and boot to desktop
2. Press the mute key (f6)

Expected result:
- When the system is muted, the LED should be lit.

Actual result:
System muted, but the LED still off.
