AMP Story是否支持默认开启声音？技术咨询

Short answer: No, you can’t set AMP Stories to play sound automatically by default. Let me break down why that’s the case, plus share some helpful workarounds to make it easy for users to enable audio:

Why default sound isn’t allowed #

• Browser autoplay policies: All major modern browsers (Chrome, Firefox, Safari, etc.) enforce strict rules against autoplaying media with sound. This is a user-centric measure to prevent unwanted noise from interrupting people’s browsing experience, and AMP fully adheres to these industry-wide policies.
• AMP’s core design principles: AMP Stories are built to prioritize user control. Defaulting to silent playback is a standard choice here—users get to decide when they want to engage with audio content, rather than having it forced on them as soon as the story loads.

Practical tips to guide users to enable sound #

• Add a clear, eye-catching prompt on your story’s first slide (like a large speaker icon paired with text saying "Tap to turn on sound") to let users know audio is available.
• Ensure the built-in audio control button in your AMP Story is prominent and easy to tap, so users can quickly enable sound once they’re ready to listen.
