Embed youtube doesn't play in slider via home page editor

I have a listing with youtube embedded.
I have a slider with caroussel in my homepage, placed by the home page editor.
The video doesn’t play.
When I disable the home page editor, the slider with carousel appears (the standard) on the home page and the embedded youtube plays.
The uploaded video (in media) plays in both situations.

BTW When I click and when they play, they don’t play on the home page, but on another page.
-how can I let play in de slider on the homepage?
-hwo cn I prevent them from playing automatically, s they do now on the other pat?
