I am using Linux mint OS since an Year , I use to consistently download updates and install , I use chrome as a default browser , when ever I open youtube and watch some video , I listen to some repetition in sound ( say repeated lyrics of song ) while it is playing , In firefox it is working fine .

What is the problem am I missing any plugin , AFAIK Chrome doesn't need a flash player plug in , It has a built in flash player . IS that the problem ?

And also previously I was not facing this , recently I started using Cinimon UI centOS after this all these kind of problems started

MY hard ware is 64 bit intel core i3 and also I have installed linux mint 64 bit

Please let me know what is the problem and how to fix this .

Thanks in advance for responding to this post
