[Freedombox-discuss] Is there some mailing list that discusses matrix clients, specifically element desktop?

Hi Augustine,

There doesn't seem to be a dedicated Matrix room for Element desktop. I 
only found this general support email: support at element.io



   As mentioned in the manual[1], Element handles audio/video calling 
for rooms with one-to-one conversations (a.k.a Direct Messages in the 
mobile app) and with rooms with larger groups differently. It uses the 
configured STUN/TURN server for the former and a Jitsi Meet server for 
the latter (default server: jitsi.riot.im). It is worth checking both 
the cases. Fixing the former case is within your control - check whether 
the Coturn app is running on your FreedomBox. Configuring your Matrix 
Synapse installation to use a different Jitsi Meet server is not yet 
implemented in FreedomBox (issue #2064).


   It could also be a client issue. One way of figuring this out is to 
install a previous version of Element desktop and see if the problem 
still exists. I don't use Element desktop myself, but I believe it's an 
Electron-based application (basically a Chromium browser running a 
single web app). It's possible that the application no longer has the 
permission to access your camera.

   Another way of making sure that it's a client issue is to use try 
using app.element.io in your browser. Give it permission to access your 
camera when prompted.

   This is less likely, but maybe your camera is not working anymore. 
Test this with a camera app e.g. Cheese on Debian.
