Thanks — I’m sorry you’re seeing the audio waveforms fail to load. I can help get this fixed, but I need a few details to diagnose the problem. Could you please share: • Platform: Are you running LiveKit on the web (React, plain JS), Flutter, React Native, native iOS/Android, or something else? • Where it fails: Is this during local development, in production, or both? • Exact error messages: Any console logs or stack traces (for web browser console, Xcode/Android logs, or Flutter logs)? Even a short copy/paste helps. • Widget or component you’re using: Are you using

AudioVisualizerWidget

,

SoundWaveformWidget

, a custom waveform component, or a third-party library? • Reproduction steps: What sequence triggers the failure (e.g., join room → publish audio → waveform blank)? • Recent changes or environment details: Did you recently upgrade LiveKit SDK, change plugins (e.g.,

flutter_background_service

), or test on a specific OS version (notably iOS versions)? • Quick checks you’ve tried: Permissions (microphone/camera), dependency updates, restarting app/browser, testing on another device. If you’re on Flutter/iOS, please mention the iOS version and whether you see a MissingPluginException — that’s a known clash with some background service plugins and I can point to exact steps to fix it. Share the above and I’ll provide targeted troubleshooting steps and a likely fix.
