Google Chrome not detecting Headset and Web cam in Kali Linux

My current version of your Kali Linux is(#cat /etc/issue) Kali GNU/Linux Rolling n l

I am using google chrome from root user using this command gksu -u ysr google-chrome (there is another user called 'ysr').

Chrome Version is 50.0.2661.86 (64-bit).

My problem is that the google chrome doesn't recognize any of devices like headset,mic and webcam. But these are working perfectly in Iceweasel browser.

Thanks.
