   {
     "speech": {
       "hotword_sensitivity": 0.6  // Higher = more sensitive
     }
   }
   ```

### Music Not Playing

```bash
# Check if files are in correct location
ls -la /home/pi/Music/

# Verify file format (MP3, WAV, OGG, FLAC)
file /home/pi/Music/song.mp3

# Test playback manually
./venv/bin/python3 -c "from music_player import MusicPlayer; p = MusicPlayer(); p.play(list(p.music_library.values())[0])"
```
