We've been trying to debug an issue where we livestream a show to participants. For a portion of them, they either don't hear any audio, or the livekit audio plays through earpiece mode and they perceive it as not playing at all. Could this be due to some kind of race condition where the LiveKitRoom instantiation is completed before the AudioSession starts?

Thanks for reaching out, Arthur. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Thank you for reaching out about the audio issues during your livestream. Based on the information available, it is recommended to start the
AudioSession
before connecting to the LiveKit room. This order of operations ensures proper audio functionality and may help resolve the issues you're experiencing. For example, the typical pattern is:
Copy code
useEffect(() => {
  let start = async () => {
    await AudioSession.startAudioSession();
  };

  start();
  return () => {
    AudioSession.stopAudioSession();
  };
}, []);

return (
  
);
Additionally, you can configure the audio session before starting it, as shown below:
Copy code
useEffect(() => {
  let connect = async () => {
    // configure audio session prior to starting it.
    await AudioSession.configureAudio({
      android: {
        // currently supports .media and .communication presets
        audioTypeOptions: AndroidAudioTypePresets.media,
      },
    });
    await AudioSession.startAudioSession();
    await room.connect(url, token, {});
  };
  connect();
  // ...
}, [url, token, room]);
Could you confirm if this order is being followed in your implementation? If not, adjusting it might resolve the issue. Let me know if you need further assistance! Sources: Expo quickstart | LiveKit Docs | GitHub::livekit::livekit_composite | livekit/client-sdk-react-native/docs/i...

yes but with this code, couldn't there be a race condition where the room is instantiated first before the useEffect hook executes?

I don't have the answer you're looking for. You could also try asking your question: • in one of the other Slack channels or • to https://deepwiki.com/livekit/livekit_composite which is trained on all LiveKit source code If you find the answer, please post it here to help others!

Current guess is that the "no audio" issue is in fact that the audio is routing to the "earpiece" audio. Seems like solution is to: 1. Migrate audio session config and initialization to App.tsx 2. Utilize the useIOSAudioManagement to ensure audio routing consistently routes to the "default" output DeepWiki Conversation: https://deepwiki.com/search/sometimes-when-users-join-the_b07ff5d1-595f-459f-9f8f-6f88b5445fae
