Guess there's a conflation of terms. I think a lot of people enjoy the "automatically play the next episode after this one ends" feature. Recently, however, Netflix has added a "blast sound out of my TV when I hover over something I might want to watch" which I never want. If I'm interested, I'll click in and watch the trailer. I rarely want it to start playing a video just cause I hovered over the title.

I can't find anywhere on the screen that doesn't make noise (and usually only after several seconds of false security). I've just stopped opening netflix unless I already know what I want to watch

Yes...that's the one I was talking about. Autoplay the next episode is fine.

Autoplay every show I barely hover over? No, thanks.

Particularly when the advert is for their show "sex education"and my young children are in the room!

Ah. Now I understand. I believe there is an option to shut this off. It really annoyed me when that happened and I remember doing some googling and shutting it off. The videos still autoplay but the sound doesnt.
