MP4 stops playing when unmuted

I am playing mp4 here starting muted, and 5 sec in made it unmuted.
In desktop, it plays well. From 5 sec in, it starts to sound well.

But in my iPhone, as soon as I unmuted it. It stops playing. Any idea?


I found the following project. I will try what they did here.

Hi @lenvanthis,

The first project link you shared seems private? I can’t open it.

But I imagine what the issue most likely is, in iOS you need to have the user interact with a page element before starting playing a video that includes audio.

Autoplay with no user interaction on iOS works only for muted videos.

By following the sample project aforementioned, we could solve the problem. What you described was the source of the problem. Thanks for the help.
