Discussion

Define a list of sites, based on URL patterns, that are allowed to autoplay media. If this policy is not configured, the global default value from the AutoplayAllowed policy (if set) or the user's personal configuration is used for all sites. EDGE-00-000024 disables the AutoplayAllowed policy.

This requirement for "AutoplayAllowlist" is not required; this is optional.

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Allow media autoplay on specific sites" may be set to "allow" for allowlisted domains.

Use the Windows Registry Editor to navigate to the following key:
HKLM\SOFTWARE\Policies\Microsoft\Edge

AutoplayAllowlist may be set as follows:
HKLM\SOFTWARE\Policies\Microsoft\Edge\AutoplayAllowlist\1 = mydomain.com
HKLM\SOFTWARE\Policies\Microsoft\Edge\AutoplayAllowlist\2 = myagency.mil

If configured, the list of domains for which autoplay is allowed may be allowlisted.
