Autoplaying videos are often muted by web browsers to improve the user experience and prevent disruptive sounds. Modern browsers, like Chrome and Safari, have implemented strict policies around autoplay, requiring user interaction before unmuted playback can occur. This means videos will autoplay, but the sound will be off by default until the user interacts with the page.
User Experience: Browsers prioritize a good user experience by avoiding unexpected loud sounds that can be annoying or startling.
Control: Muting autoplay gives users control over when and if they want to listen to the audio.
Power Consumption: Muting autoplay can also help conserve battery life on mobile devices.
User Interaction:
After a user interacts with the page (e.g., clicks, taps), browsers may allow autoplay with sound.
Media Engagement:
Some browsers have a Media Engagement Index, and if the user has previously played videos with sound on the same domain, they may be allowed to autoplay unmuted.
Allowlisted Sites:
Certain websites, like major video platforms, may be automatically allowed to autoplay unmuted based on their reputation and the user's engagement history.
In summary, browsers mute autoplay to prevent intrusive sounds and give users control, while allowing unmuted playback after user interaction or for specific sites with a good track record.
