Autoplaying Dubb videos with sound

Dubb product owners,

Please clear my doubt - I would like to ask whether the current versions of browsers (both Chromium-based and Firefox) are interfering with the Dubb script behavior? When embedding a video on a website page I set the video to autoplay (tried both on page and in widget) and it works. However, when I also set the script to autoplay with sound the video is not playing automatically and page visitor needs to click on the player in order to start the playback.

Is it the browsers caring too much about user experience and blocking automatic playback with audio or there is currently something in the Dubb backend that needs adjustment or fixing?

Thanks in advance
