Nextcloud Talk Conference (w/o mic and camera)

A few of my friends tried to conference using nextcloud, however we find that if one does not accept the activation of mic and camera, he/she will not receive video share from others. how do we remedy this? can someone participate in nextcloud conference without activating mic and camera?

What version of the Talk app?

(I assume you’re referring to the web?)

Hi Mario, yes. I am working on Nextcloud 13 on my browser.

What version of the Talk app on the server?

version 13.

cc @nickvergessen who can maybe assist.

Version 13 is Nextcloud, not the Talk app btw.
Also mention browser, etc

Since Talk 3.2 you should be able to participate without having a mic/camera yourself. So just make sure you updated your version to the latest.
