I don't know why but the easyscreencast preinstalled in Kali 2.0 doesnot record audio. It just records the plain audioless video. I've searched in google but found no any help as it contains no any info on EasyScreenCast but other recording things. Here is a ScreenShot:

I checked mark on Record Audio on Top Panel and selected analog-input-internal-mic as Input Source Audio on Screencast options.
I would appreciate any help on this matter.
