Signed into FB from Chrome (version 47) from my MacBook (Mavericks).<p>It was 6am and I had my earbuds in and I could tell they turned on. They didn&#x27;t turn off until a few minutes after I logged off.<p>I went to YouTube just to check. A few minutes after I closed my YouTube tab, I could hear the audio disengage.<p>I&#x27;m wondering if it&#x27;s connected to FB autoplay videos, but those have no sound.
