Video autoplay
When on, the inline player starts playback automatically in muted mode (browsers block unmuted autoplay without a gesture).
Where to find it
Admin → Settings → Mods → Video previews → Auto play
Setting key: toggle.video_mod_autoplay
Default: off (must be explicitly enabled)
Common problems

Browser policy, or expecting sound - autoplay is muted by design. User can unmute in the player.
