Screen sharing with audio doesn't ignore jitsi's output

[BigBoss1941]

Description

As title suggest, when ScreenSharing with audio enabled, other participants in the call will hear themselves in the audio, since jitsi fails to isolate it's own output.

Current behavior

Jitsi output is shared with the audio streamed to the ScreenShare

Expected Behavior

Jitsi should not stream other participant's audio stream into its own ScreenShare Audio stream

Possible Solution

No idea.

Steps to reproduce

Get in a call with two participants, both with microphone activated, and enable ScreenSharing with audio.
Once someone talks, there should be an Echo-like audio feedback.

Environment details

• Windows 10
• Intel CPU + Nvidia GPU if it matters.

@jallamsetty1 I think this is also another reason to move to gDM in Electron, IIRC that code path does enable the echo canceller but the gUM path doesn't, and patches to fix that have been rejected.

Yes! I will scheduling this work as part of the new LJM APIs for track creation/addition.
