Canvas BigBlueButton integration cannot join the audio in breakout room

[vinebranch]

Hi

When testing Canvas and BigBlueButton integration, there is an issue that only happened in the Breakout Room. It does not happen if just in the main conference room from Canvas.  If creating a conference from BigBlueButton server's GreenLight UI, there is no problem in the Breakout Room.

To reproduce the error, Creating 2 Breakout Rooms, click "Ask to join" or "Join Audio" > select Microphone for the question, How would you like to join the audio?

I am getting the following error message:

There was an issue with your media devices
Did you give permission for access to your microphone? Note that a dialog should appear when you try to join audio, asking for your media device permissions, please accept that in order to join the audio conference. If that is not the case, try changing your microphone permissions in your browser's settings.

Note that the audio was working in the main conference room. I did not see any meaningful error message in Canvas, /var/log/apache2/error.log or /var/canvas/log/production.log

Can someone shed some light on how to debug this?

My canvas server is ubuntu 20.04, download 4/1/2024 production code.

BigBlueButton server spec are 

BigBlueButton Server 2.7.6 (584)
Kernel version: 5.15.0-1058-aws
Distribution: Ubuntu 20.04.6 LTS (64-bit)
Memory: 16227 MB
CPU cores: 4

Thanks,
