Modern browsers often block videos from autoplaying with sound. HeySummit’s Start stream muted option helps supported videos and streams begin muted, then lets attendees unmute them. It does not guarantee autoplay.
Enable Start stream muted
Go to Content & Schedule > Sessions, open the session’s Actions > Manage Session, then open Broadcast.
Choose the broadcast type and provider. Under Playback options, turn on Start stream muted when that provider supports it.
Select Save and Close.
Check playback
Use this alongside the relevant autoplay setting when you want playback to begin automatically. Availability depends on the selected provider. Autoplay still depends on the attendee’s browser, device and provider; the attendee may need to press play. If Start stream muted is off, a browser that blocks autoplay with sound may wait for a click. See Chrome’s autoplay policy for one browser’s rules.
