+# iOS — mute audio in diretta (allineamento da Mac)
+
+Documento operativo per **Cursor su Mac**: verificare e, se serve, ritoccare l’app iOS dopo il ramo `feature/stream-audio-mute`.
+
+**Aggiornato:** 2026-08-12  
+**Branch:** `feature/stream-audio-mute` (parte da `main`)  
+**Android di riferimento:** mute microfono in overlay + sync regia  
+**API produzione:** `https://www.matchlivetv.it`
+
+Il codice iOS è **già nel branch** (engine, overlay, API, Cable, L10n). Su Mac va **compilato, testato su device** e, se HaishinKit 2.2.5 rifiuta un parametro, adattato come sotto.
+
+---
+
+## Perché esiste
+
+In palestra la musica di sottofondo finisce nel microfono del telefono. Il relay YouTube fa `-c:a copy`, quindi YouTube sente quella musica e può reclamare il copyright.
+
+Il mute **non ferma** lo stream: continua video + overlay + AAC, ma i sample audio sono silenzio.
+
+---
+
+## Contratto API / Cable (già in backend)
+
+| Pezzo | Dettaglio |
+|-------|-----------|
+| Campo sessione | `audio_muted` (boolean, default `false`) in JSON sessione e `GET/POST /regia/:token/status.json` |
+| REST app | `PATCH /api/v1/sessions/:id/audio_mute` body `{ "muted": true \| false }` |
+| REST regia | `POST /regia/:token/audio_mute` body `{ "muted": true \| false }` (senza body: toggle) |
+| Cable command | `{ "type": "command", "action": "mute_audio" \| "unmute_audio", "muted": true \| false }` |
+| Cable event | `{ "type": "stream_event", "event": "audio_muted", "muted": true \| false }` |
+
+Idempotente: se lo stato è già quello richiesto, il backend non reinvia eventi.
+
+---

+
+## Engine HaishinKit 2.2.5 (punto da verificare su Mac)
+
+Implementazione attesa in `LiveBroadcastEngine`:
+
+```swift
+func setAudioMuted(_ muted: Bool) async {
+    audioMuted = muted
+    await applyAudioMute()
+    metrics.audioMuted = muted
+    emitMetrics()
+}
+
+private func applyAudioMute() async {
+    guard pipelineConfigured else { return }
+    var settings = await mixer.audioMixerSettings
+    settings.isMuted = audioMuted
+    var track = settings.tracks[0] ?? AudioMixerTrackSettings(downmix: true, channelMap: [0])
+    track.isMuted = audioMuted
+    settings.tracks[0] = track
+    try? await mixer.setAudioMixerSettings(settings)
+}
+```
+
+In `configurePipeline` i settings iniziali passano `isMuted: audioMuted` sia sul mixer sia sulla track 0.
+
+**Se il build fallisce:**
+
+1. `AudioMixerSettings` potrebbe non avere `isMuted` nel memberwise usato oggi — in quel caso muta solo `settings.tracks[0].isMuted`.
+2. `setAudioMixerSettings` è `async throws` nel codice attuale; se la signature è sync, togli `try await`.
+3. Non staccare il microfono (`attachAudio(nil)`): YouTube/MediaMTX vogliono AAC continuo. Mute = silenzio, non assenza di traccia.
+
+Dopo `prepareBroadcast` / `resumeBroadcast` la schermata richiama `setAudioMuted(session.audioMuted)` per riallineare lo stato persistito.
+
+---
+
+## UI overlay
+
+Toolbar destra (come Android), sotto pausa:
+
+| Stato | SF Symbol | Chiave L10n |
+|-------|-----------|-------------|
+| Audio on | `speaker.wave.2.fill` | `broadcast.mute.cd` |
+| Audio off | `speaker.slash.fill` | `broadcast.unmute.cd` |
+
+Bottone `highlighted` quando mutato (stesso verde della pausa). Pannello telemetria: riga `broadcast.audio.muted.label` se mutato.
+
+---
+
+## Chiavi L10n (già aggiunte, 5 lingue)
+
+| Android | iOS |
+|---------|-----|
+| `broadcast_mute_cd` | `broadcast.mute.cd` |
+| `broadcast_unmute_cd` | `broadcast.unmute.cd` |
+| `broadcast_audio_muted_label` | `broadcast.audio.muted.label` |
+| `broadcast_snackbar_muted` | `broadcast.snackbar.muted` |
+| `broadcast_snackbar_unmuted` | `broadcast.snackbar.unmuted` |
+| `broadcast_snackbar_muted_remote` | `broadcast.snackbar.muted.remote` |
+| `broadcast_snackbar_unmuted_remote` | `broadcast.snackbar.unmuted.remote` |
+| `broadcast_snackbar_mute_error` | `broadcast.snackbar.mute.error` |
+
+---
+
+## Test su Mac (acceptance)
+
+1. `cd native/ios && python3 generate_xcodeproj.py`
+2. Build simulatore / device.
+3. Avvia una diretta (anche verso ambiente di staging).
+4. Overlay: tap mute → icona speaker.slash, snackbar «Audio silenziato», telemetria «Audio off».
+5. Apri la **regia** sullo stesso match → il pulsante deve dire «Riattiva audio».
+6. Dalla regia riattiva → il telefono mostra speaker.wave e snackbar «dalla regia».
+7. Mute, metti in **pausa**, riprendi: l’audio resta mutato (stato persistito).
+8. YouTube / player HLS: video continua, audio silenzioso (non assente).
+9. Unit test: `LiveBroadcastCoordinatorTests.testAudioMuteCommandFromCable`.
+
+```bash
+cd native/ios
+python3 generate_xcodeproj.py
+xcodebuild -project MatchLiveTv.xcodeproj -scheme MatchLiveTv \
+  -destination 'generic/platform=iOS Simulator' \
+  -derivedDataPath build/DerivedData \
+  ONLY_ACTIVE_ARCH=YES ARCHS=arm64 EXCLUDED_ARCHS=x86_64 \
+  build
+```
+
+---
+
+## Criterio “fatto”
+
+- [ ] Build iOS senza errori HaishinKit
+- [ ] Mute/unmute locale in overlay
+- [ ] Sync bidirezionale con la regia via Cable + REST
+- [ ] Mute sopravvive a pausa/ripresa
+- [ ] AAC silenzioso in onda (niente drop della traccia audio)
+- [ ] Stringhe IT/EN/FR/DE/ES visibili in overlay
