Have you considered building zoom for the Raspberry Pi 4 linux system?

I have not tried Zoom with Firefox on my RPI4 recently. It appears though audio support may have been added:

Firefox Computer Audio "Not Supported" -- Don't Lie To Me!

Hi @sales1, This was a decision made by our fellow Engineers to not use polyfill at the time and to use Chrome to ensure our customers have best meeting experience as possbile. Once Audio worklet is released for Firefox, we’ll be more than happy to include it within the list of supported browsers for computer audio. Thanks

Normally I just use Chromium and experience laggy and freezing video.

I have tried the setpci “fix” suggested on the Raspberry Pi forums but no luck there.

Also we know the Chrome web app won’t work because Chromium doesn’t support Native Client anymore.
