video/music autoplay won't work

hi, i really want to have a song that autoplays on my profile but nothing that i try seems to work. which is strange, because back in december it did and it also works on the css preview website that i use. just not on spacehey itself.

it does show the video but you have to actually click on it so it starts playing. 

these codes dont seem to work for me, though i dont even know if there are others:

<iframe width="0" height="0" src="https://www.youtube.com/embed/xxxxx?autoplay=1" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen=""></iframe>

<iframe width="0" height="0" src="https://www.youtube.com/embed/eXjhmwueQQM//?&;amp;;autoplay=1&;loop=1&;controls=1" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" loading="lazy"> </iframe>

i'm using google chrome.
