Zoom - errors about audio, video not supported

[pocock]

Zoom has test site at https://zoom.us/test

It always gives an error "Your browser does not support using the computer's audio device"

Looking at the JavaScript web console, there are some messages like this

Code: [Select]

Uncaught TypeError: i.a.sendSocket is not a function
    O https://st1.zoom.us/web_client/6sh2md/js/webclient.min.js:1
    h https://st1.zoom.us/web_client/6sh2md/js/webclient.min.js:1
    Lodash 3

One person suggested bugs with slow download of resources but I'm on gigabit fibre.  An x86 laptop on the same fibre connection does not give the problem.  This issue could be a red herring.

Both laptop and Talos II are running Firefox 78.7 ESR

One difference I notice: the Talos II always shows the captcha, the laptop always bypasses the captcha

Does anybody have any insights into this or workarounds?

Will a newer Firefox build fix it?

I'll have a look at this this evening, but assuming there is an issue, I can't really debug this myself because of the nature of my firewall.

Thanks, even if you can offer hints for other people to debug it would be very welcome

I got your other E-mail. I'll have a look later today (working this weekend).

There is at least one support request open with Zoom about this.

Can anybody else confirm either you have the problem too, or it works fine on your system?

Please also share the Firefox build (e.g. Debian, Fedora, version number, ...)
