Sharing audio is only possible in certain browsers. Check browser support on MDN's compatibility table.
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:
Subscriber
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>').getTrack('screen_share_audio')
