Thanks for reaching out, Gopi. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
It looks like you're encountering the error "timeout waiting for pre-connect audio buffer," which means the system didn’t get the pre-connected audio buffer data within the expected time. This often happens if the agent takes a bit longer to connect, subscribe to the track, or become active. Here are a few friendly suggestions to help you resolve this: 1. Adjust timeout settings: Try increasing the
pre_connect_audio_timeout
value in
RoomInputOptions
on the agent side. This gives the system a little more time to receive the audio buffer. 2. Ensure proper agent configuration: Double-check that the agent participant is set up correctly to receive pre-connect audio by registering the
PreConnectAudioHandler
before connecting to the room. 3. Client-side preparation: For mobile clients, it helps to call
AudioManager/setRecordingAlwaysPreparedMode(_:)
during app launch. This way, microphone permissions are requested early, which can prevent any delays in capturing audio. If you’d like, I’m here to help you walk through these steps or answer any questions you have along the way.

Can you give me code snippet to add
pre_connect_aRoomInputOptionsudio_timeout
in
RoomInputOptions

I'd love to help you set the
pre_connect_audio_timeout
in
RoomInputOptions
for LiveKit! Here's a little code snippet that should do the trick:
Copy code
from livekit.agents.voice.room_io import PreConnectAudioHandler

handler = PreConnectAudioHandler(
    room=room,
    timeout=5.0  # Audio will be ignored if not received within 5 seconds
)
If you have any questions or need a hand with anything else, please don't hesitate to reach out. I'm here to help! Sources: livekit-agents/livekit/agents/voice/room_io/_input.py

Should I need to pass this handler to
RoomInputOptions
?
