How to set layout video un-mute with API 4.0

hi all, when I use API4.0 to create a fullscreen layout to display a video, it is set to mute by default.
so how can I set to un-mute? i use this API to attach the video:(Swagger UI), but it does not have a mute paramter

Hi @jiangping.gl , the video module is set to mute videos by default in v4.

You can change this by navigating to the Modules page of your CMS, then locate and click on the row menu for the Video module, and select Configure.

Once you’ve unchecked the box and clicked on Save, you should find that the videos are no longer muted by default.
