This extension allows you to auto unmute yourself on google hangouts.
Ever get tired of clicking on the microphone icon in a Google+ Hangout each time you get muted, to un-mute yourself? This extension automates that process by detecting when you are muted by another participant within the hangout and instantly un-mutes your audio.
There is an user specified response time when using this extension so you can manually set the time in milliseconds that you would like the extension to react to you being muted. Setting it to 50 is the standard.
