Comment 161 for bug 1516025

Created attachment 255623
After reboot

Followed the Above on my Alienware 18 running Linux Mint 18.1

I did everything in the list above

apart from "Click on your Volume Icon on the top (Ubuntu Unity) and remove the marker 'mute'."

as It didn't show anything different in my Sound properties

The attachment shown is after a reboot

So its back to the drawing board for me
Cheers
