Hi, if i create a Livekit-Room in Javascript the browser ask me for microphone permissions. But I haven't requested the microphone. Is it possible to disable this initial room behavior?

Thanks for reaching out, Stefan. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Hey there! If you want to avoid the browser asking for microphone permissions right away when creating a LiveKit room in JavaScript, you can tweak the room settings so it doesn’t need audio input from the start. Here are a few friendly options for you: • Turn off the microphone by default:
Copy code
// Turn off microphone by default
await room.localParticipant.setMicrophoneEnabled(false);
• Skip audio capture completely:
Copy code
const room = new Room({
  audioCaptureDefaults: {
    enabled: false,
  },
});
• Stop the microphone track when muted:
Copy code
await room.localParticipant.setMicrophoneEnabled(false, undefined, {
  stopMicTrackOnMute: true,
});
These settings make sure the microphone won’t be accessed unless you choose to turn it on later. If you have any questions or need a hand with this, just give me a shout—I’m here to help! Sources: Camera & microphone | LiveKit Docs | src/room/participant/Participant.ts | quickstart/src/index.js

The browser permission dialog come inside the 'new Room(..)' statement.

Hey there! The browser permission dialog popping up during the 
new Room()
statement happens because LiveKit starts setting up audio and video tracks right away. To avoid surprising your users with permission requests too early, here’s a friendly way to handle it: • Ask for permissions explicitly before creating the room:
Copy code
// Ask for permissions before initializing the room
async function requestPermissions() {
  try {
    await navigator.mediaDevices.getUserMedia({ video: true, audio: true });
  } catch (err) {
    console.error('Oops, there was an error requesting permissions:', err);
  }
}

requestPermissions().then(() => {
  const room = new livekit.Room();
  // Now you can safely set up the room
});
• Try using the 
prepareConnection
method: `room.prepareConnection(url, token);`This helps get things ready behind the scenes before the user actually connects, which can cut down on those permission pop-ups. Following these tips should make the permission dialogs a lot less intrusive when creating a room. If you want me to walk you through any part or have more questions, just give me a shout!

I want the the permission dialog comes later, if the user enables the microphone, or never if the user do not publish anything.
t
To make sure the microphone permission dialog only pops up when the user actually decides to enable the microphone (or doesn’t show up at all if they never publish anything), you can control exactly when those permissions get requested: 1. Start the room with the microphone turned off:
Copy code
// Disable microphone by default
await room.localParticipant.setMicrophoneEnabled(false);
2. Ask for microphone permissions only when the user chooses to enable it:
Copy code
// Enable microphone on user action (e.g., button click)
document.getElementById('enableMic').addEventListener('click', async () => {
  try {
    await room.localParticipant.setMicrophoneEnabled(true);
  } catch (error) {
    console.error('Error enabling microphone:', error);
  }
});
This way, the browser will only ask for permission when the user explicitly wants to use the microphone. If you run into any issues or want to chat more about this, just let me know—I’m here to help! Sources: README.md
