Webex web app no Audio support

Hello. I need to run Webex meetings on my manjaro laptop but i dont get audio support "The web app doesn’t support using your computer to connect to audio, which is the only audio connection option that is supported for this meeting. "
I installed jdk-openjdk 15. i use Firefox 84 and chrome.
Thank you.

Sounds like a limitation of the Webex software.
I had the same issue with Zoom on FF. Had to use the desktop app to get audio working.

i was using webex on manjaro before . it was working on firefox. i cant remember what i did before to work. i had to do i clean installation of manjaro nibia and seens then i have the problem.
