Windows Registry Editor Version 5.00 ; Allow autoplay for ViewSpace production and any subdomains ; https://learn.microsoft.com/en-us/deployedge/microsoft-edge-browser-policies/autoplayallowlist ; This entry did not work as planned for us, but the documentation clearly indicates this should work. [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\AutoplayAllowList] "viewspace_production"="https://viewspace.org" "viewspace_subdomains"="[*.]viewspace.org" ; WORKAROUND: Toggle global autoplay policy (1 = allowed everywhere, 0 = blocked except allow list) ; https://learn.microsoft.com/en-us/deployedge/microsoft-edge-browser-policies/autoplayallowed ; This is a workaround. Since the domain specific AllowList entries did not work, we fell back to allowing autoplay for every site. [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge] "AutoplayAllowed"=dword:00000001
