Flame master , Gecko 10853dd and Gaia cc5af5e.

Tested using unagi 1.3 and unagi 2.0, this option worked properly. 

Actual results:

The video sound isn’t muted. This happens with video is showing in fullscreen or in normal size. 

Expected results:

The video sound should be muted when you pressing the mute button.

[Blocking Requested - why for this release]:

Buttons should always function properly when tapped so nominating this 2.1? This is also a regression from 2.0

Gaia is the same again, so it's a Gecko issue.

Gecko pushlog:

There are quite a few audio related commits. All from the same author.

The commits here seem to be the root cause for bug 1052923. Reverting both of them fixes the problem however I'm unsure if the issue is really caused by this or we miscalculated the volume in the gaia application in the first place.
This landed before uplift, so it's already in v2.1.
