hi! thread your messages please :slightly_smiling_face:

How can I screen share with audio in the client SDK for flutter?

when screen sharing only the video track is published

flutter native audio screen sharing is not yet supported; you can follow <https://github.com/livekit/client-sdk-flutter/issues/316|this issue> for updates.  <@U02GAC58A79> might have comments as well

The comment on that issue suggest that it does support chrome browser,

But Even with chrome browser i'm not getting audio

You can try to capture a tab with music playing on Chrome instead of the entire Chrome window, for example, open a YouTube page in Chrome.

In addition, Chrome’s screen sharing cannot capture the sound of apps other than Chrome.

<@U02GAC58A79> How can i capture just a tab?

the `ScreenSelectDialog` dialog only shows entire screen or windows

electronjs apps can capture system audio without issues, maybe you guys should have a look at how it is implemented in the <https://www.electronjs.org/docs/latest/api/desktop-capturer>
api

<@U02GAC58A79> I tried to achieve screen sharing audio using the  `stereo mix` device that realtek drivers provide, and it seems to work, but with issues, the stream is being sent to the other end but after a few seconds the stream starts to crack or stop completely

Another issue is that as soon as `setMicrophoneEnabled` is called, the system audio is reduced for some reason which causes the stream to have very low volume

Also, someone posted some code in `C++` for adding desktop capture here <https://github.com/flutter-webrtc/flutter-webrtc/issues/1273>
Can't we add this to the wrapper that `flutter_webrtc` is using
