Public bug reported:

Description of problem:
The F6/mute key on the keyboard of HP notebooks often has a built in LED 
indicator to show if the sound is muted. The LED state is never toggled. It 
will just retain its state, even though the audio is succesfully muted/unmuted.

Tested with HP Envy 15 from 2015. HP Stream 11 from 2015 and HP Stream
11 from 2016.

Version-Release number of selected component (if applicable):


How reproducible:
Always.

Steps to Reproduce:
1. Press mute key on HP laptop

Actual results:
Mute state in software toggles, LED in mute key does not.


Expected results:
Mute state in software and LED in mute key toggle.


Additional info:
This happens on kernel 4.8, 4.9 and 4.10. I have not tested any other versions.
