Autoplay, also called Auto Start, asks a gallery to begin playing when it loads. The viewer's browser still decides whether playback is allowed.
Available controls vary by template. If the setting is absent, check the template-specific help from the customization screen or select an appropriate gallery layout.
Browsers commonly block automatic playback with sound until the visitor interacts with the page. Muted video is more likely to autoplay, but user preferences, device policies, power-saving modes, and iframe permissions can still affect the result.
For an audio gallery, keep a visible Play control and expect the listener to click it. Do not rely on background audio starting on every visit. For video, use muted playback where the template supports it and let the viewer choose when to enable sound. Chrome explains its rules in the autoplay policy guide.
Use the complete generated embed code. For iframe embeds, preserve the permissions in that code and check that the host site permits autoplay. Test on mobile as well as desktop, including a visit with no previous interaction.
Autoplay and playing the next item in a playlist are separate settings. Verify both when configuring an audio gallery or a video playlist.
