My video autoplays but sound is not working
All modern browsers will autoplay videos as long as they are muted.
Consequently, if the mute option is selected, the experience will be consistent on all modern browsers.
However, browsers have different policies on autoplaying videos with sound. Particularly:
- Chrome will only autoplay videos with sound after the following user interactions: mouse move, mouse click, page scrolling, typing or mobile screen touching. Additionally, on mobile, Chrome may not play the video automatically if the 'Data saver' option is on.
- Firefox will autoplay videos with sound in all cases
- Safari will only autoplay videos with sound after the following user interactions: mouse click, typing or mobile screen touching
- Edge will autoplay videos with sound in all cases
In order to have the most consistent experience on all browsers, our app will start video playing with no sound and, depending on the browser, will enable sound if possible (normally after a user interaction).
Although the autoplay video compatibility is consistent on all modern browsers, some older versions of the browsers work differently.
Particularly, old versions of Android Browser (deprecated) and Safari mobile (iPhone 6 or earlier), the videos cannot be played automatically. A transparent play button in the middle of the video is shown which can be pressed to start playing the video.
