Check Text ( C-55131r808526_chk )
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

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

If configured, the list of domains for which autoplay is allowed must be allowlisted; otherwise, this is a finding.

If this machine is on SIPRNet, this is Not Applicable.
