Thanks — I see you're hitting an error because you're trying to use a built‑in clip named

CROWDED_ROOM

. That clip isn't available and the agent is raising an attribute error for the enum member. What you can do: • Built‑in clips available right now: BuiltinAudioClip.OFFICE_AMBIENCE, BuiltinAudioClip.KEYBOARD_TYPING, BuiltinAudioClip.KEYBOARD_TYPING2.

CROWDED_ROOM

is not supported. • You cannot register new built‑in clips. To use a custom ambient (e.g., crowded room), provide your own audio file and use the BackgroundAudioPlayer. Example:

background_audio = BackgroundAudioPlayer(
    ambient_sound="/path/to/crowded-room.mp3"
)

Make sure the file path is correct and the agent process can read the file. If you want, tell me: • the code snippet you’re using (so I can point out the exact change), and • the audio file format/path you plan to use — I’ll help you plug it in. Sources: Agent speech and audio | LiveKit docs
