+### AFK Auto-Mute in Voice (P5-11)
+
+Automatically mutes the microphone after a configurable period of microphone-on silence.
+
+**Implementation:**
+
+- `useAfkAutoMute(callEmbed)` hook opens a separate monitoring-only `getUserMedia` stream (independent of Element Call's stream) and analyzes it via `AudioContext` + `AnalyserNode`
+- RMS level is sampled every 500ms; if it stays below threshold while the mic is on, the silence timer starts
+- After the configured timeout (`afkTimeoutMinutes` setting), `callEmbed.control.setMicrophone(false)` mutes the mic and an in-app toast is shown
+- Monitoring stream and `AudioContext` are fully cleaned up on unmount (no resource leak)
+- Activated inside `CallControls` via `useAfkAutoMute(callEmbed)` — no changes required to `CallEmbed` or Element Call
+
+**Settings (Settings → Calls):**
+
+- **AFK Auto-Mute** toggle (default: off)
+- **Idle Timeout** dropdown — 1 / 5 / 10 / 20 / 30 minutes (shown only when enabled; default: 10 minutes)

+Room and space admins are notified in real time when users knock on a restricted room.
