Summary

Safari can report an AirPlay connection while the visualizer or effects still owns the media element. Detect every captured source and offer a native reload that preserves playback state and stays native across later playback, resizing and reloads.

 AirPlay handoff
- captured media → open picker
+ captured media → restore native playback → open picker

Control Center handoffs expose the same recovery action without automatically reloading. Explicit local active-effect edits can resume DSP; remote edits, master-off edits and resets retain native mode. Current mobile DSP opt-in, master bypass, presets and VU artwork are preserved.

Evidence

  • Before: untouched dev (a36666e) failed 15 of the original 20 routing/playback cases.
    After: npm test passes all 117 tests (73 CJS and 44 TypeScript), including 26 new regressions for native-mode persistence, Control Center recovery, storage failure, one-time playback restoration and advanced master controls.
  • npx tsc --noEmit --project tsconfig.json, npm run build --ignore-scripts, JavaScript syntax and diff checks pass.
  • Add PR validation on Node 22 and 24; refresh the player cache to v59.
  • The reporter confirmed working AirPlay playback after deploying the repair. This dev adaptation was revalidated with the automated checks above; the exact physical device/receiver profile was not recorded.

Merge Danger

Door: two-way

Revert the frontend changes to roll back; saved effects and auto-resume preferences are retained.

Blast Radius: Playback

Browser audio capture, native restoration and AirPlay route recovery.

🎯 核心变更

本次 PR 修复 Web Audio 捕获音频元素后无法直接使用原生 AirPlay 的问题。恢复原生播放时,播放器会替换本地音频元素并尽量恢复播放状态,不需要重载页面;路由切换时会提示用户操作,不会自动恢复或重载。

📝 主要改动点

  • playback.js 新增 LXPlayback.replaceLocalElement(),用于替换本地音频元素、恢复媒体状态,并阻止旧元素事件影响播放器。
  • sound-effects.js 增加原生播放优先状态和音频图释放流程。移动端默认使用原生播放;用户显式启用音效或编辑本地音效时,才可切换到本机 DSP。
  • 无线投播期间锁定本地音效控件。原生播放模式下保留音效配置,但不启用本机 DSP。
  • visualizer.js 在原生播放优先时使用独立循环,并在音频元素替换后释放旧资源、重新初始化。
  • airplay.js 使用 needsNativeRestore() 判断是否需要恢复;检测到 Control Center 发起的无线投播时,会提示用户恢复原生播放并重新选择设备。
  • 新增 AirPlay 原生切换回归测试,覆盖音频元素替换、播放状态恢复、路由处理和音效模式切换。
  • 新增播放器验证工作流,在 Node.js 22 和 24 环境运行测试和构建。
  • 更新搜索状态显示逻辑、音效面板状态样式和相关文档。Service Worker 缓存版本更新至 v62。

⚠️ 影响与注意事项

  • 恢复原生播放会替换本地音频元素,不会重载页面。若浏览器拒绝继续播放,播放器会暂停并提示用户手动继续。
  • 原生播放优先状态会阻止后续播放操作自动启用音频捕获。
  • 当前未提供该分支已完成的 CI、构建或测试结果。

Merge Risk: Minimal · previous review a04da

The change restores native AirPlay playback after audio capture by replacing the media element in place. The earlier concerns about reverb edits pulling playback back into local processing appear to be addressed. No remaining merge-blocking risk was found. Testing used simulated environments rather than a real AirPlay device.

(6 skipped: 5 unsupported, 1 too large.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

阻止远程编辑的动画回调退出原生模式。

远程播放时修改混响会启动滑块动画。如果动画帧执行前切回本机,回调会通过 setReverbGain 调用 ensureLocalGraph,清除原生播放偏好并可能捕获媒体元素。应保留设置保存和本机编辑行为,同时阻止远程编辑启动的动画退出原生模式。

重置混响时保留原生播放模式

原生模式下,如果均衡器等其他音效仍启用,关闭混响会清除原生模式并可能重新捕获媒体元素,导致 AirPlay 需要再次恢复原生播放。应让关闭混响保留原生模式,同时保留已有音频图的更新行为。

修改建议

-            if (ensureLocalGraph()) updateReverb();
+            if (!(id === 'none' && preferNativePlayback) && ensureLocalGraph()) updateReverb();

增加其他音效仍启用时重置混响的回归测试。
