AutoplayAllowed must be set to disabled.

This policy sets the media autoplay policy for websites.

The default setting "Not configured" respects the current media autoplay settings and lets users configure their autoplay settings.

Setting to "Enabled" sets media autoplay to "Allow". All websites are allowed to autoplay media. Users cannot override this policy.

Setting to "Disabled" sets media autoplay to "Limit". This limits websites that are allowed to autoplay media to webpages with high media engagement and active WebRTC streams. Prior to Microsoft Edge version 92, this would set media autoplay to "Block". Users cannot override this policy.

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Allow media autoplay for websites" must be set to "disabled".
