Allow media autoplay for websites

This policy controls media autoplay behavior for websites. If you don't configure this policy, Microsoft Edge uses the current media autoplay setting, and users can change their autoplay settings. If you enable this policy, media autoplay is set to "Allow". All websites can autoplay media, and users can't override this setting. If you disable this policy, media autoplay is set to "Limit" in Microsoft Edge version 148 and later. Autoplay is limited to webpages with high media engagement or active WebRTC streams, and users can't override this setting. In versions 92 through 145, disabling this policy also set autoplay to "Limit". In versions 146 and 147, disabling this policy set autoplay to "Block". Tabs must be closed and reopened for this policy to take effect.
