Hi team,
I’m working on a MetaHuman project in Unreal Engine 5 on a Mac Studio (Apple M2 Ultra). A colleague set up the project before leaving, and I’m continuing the work without deep Unreal/Convai experience.
**What works:**
- MetaHuman is in the scene, positioned and facing the camera
- Natural idle pose (body animation is working)
- Convai Chatbot component added, Character ID connected
- ConvaiFaceSync component added, “Toggle Blendshape or Viseme” is enabled
- Text chat works: I type a message and the character responds with text
- Voice input works: I hold T, speak, and the character responds (in text)
**What doesn’t work:**
- No TTS audio output at all — the character never speaks aloud
- No lip sync / facial animation when responding
- Unreal itself can play audio fine (tested StarterContent sound files)
- Mac system audio works (YouTube, other apps)
- Microphone permissions for Unreal are granted in System Settings

**Character setup on convai.com:**
- Language: German
- Voice: assigned (tested multiple German / multilingual voices)
- Character was updated and saved
**Questions:**
1. Is there a known issue with Convai TTS audio on macOS (Apple Silicon / M2)?
2. Is there a setting in the Chatbot or FaceSync component that could be blocking audio playback?
3. Are there specific logs I should check to debug this?
Thanks in advance for any help!
