Hearing sound on Facebook auto-playing videos, before taping

Hi,


Is anyone else hearing the audio playing on Facebook auto-playing videos, before taping on them? This has been happening to me for the last few days, its not on every video, just some of them. I think they are testing a new "feature".
 It's a very jarring user experience.Anyone else saw this, or have any thoughts on it?


Please help.

I didn't find the right solution from the Internet.
