Mute and Volume not reported correctly

[GoogleCodeExporter]

What steps will reproduce the problem?
When using google chrome as the sender, if the user uses the plugin to mute or 
unmute media, an event is not triggered for the current media session update 
listener (pressing play or pause from the plugin will trigger the event).  Also 
the volume.muted property is always false, even when the audio is in fact 
muted.  The volume.level property is always 1 even if the volume is set to 50%.

What version of the product are you using? On what operating system?
Windows 7 Chrome.

Please provide any additional information below.

Please refer to the Chromecast Github sample apps 
(https://github.com/googlecast), in particular the CastVideos-Chrome app, on 
how to handle mute and volume change events. If you believe there's still an 
error, please provide receiver logs along with a detailed list of steps to 
reproduce it and we can reopen the ticket.

I have validated that the sample CastVideos-Chromesender also has the bugs I 
noted.

This is specifically what the volume property of currentMediaSessoin looks like 
when the volume is set to 40% and muted:
volume: chrome.cast.Qc
level: 1
muted: false
