Share browser audio

Assuming your client has already connected to a LiveKit Room:

const tracks = await localParticipant.createScreenTracks({
  audio: true,
});

tracks.forEach((track) => {
  localParticipant.publishTrack(track);
});

When sharing audio, make sure you select a Browser Tab (not a Window) and ☑️ Share tab audio, otherwise no audio track will be generated when calling createScreenTracks:

On the receiving side, you can use RoomAudioRenderer to play all audio tracks of the room automatically, AudioTrack or your own custom <audio> tag to add the track to the page. If you don't hear any sound, check you're receiving the track from the server:

room.getParticipantByIdentity('<participant_id>').getTrackPublication('screen_share_audio')
