(Canary 449) Audio screenshare takes long to activate sometimes & other user in voice call can hear themselves with the shared audio

Summary

In latest Fluxer canary when trying to screenshare with audio, the audio sharing takes atleast a couple of minutes to actually work sometimes, the other problem is the other user can hear themselves in the screenshare with the audio Audio sharing is pretty low audio aswell, almost like its picking up the audio through a different pipewire node that isn't the game audio.

Steps to reproduce

1. Install canary fluxer
2. Try to screenshare with audio
3. Notice it takes a while for the audio to be shared
4. User can hear themselves in the screenshare audio aswell
