TLDR: The r/selfhosted subreddit has a Discord server. The owner’s account got hacked leaving the server in a precarious state. They submitted a support ticket, but Discord has not taken action in weeks and probably won’t at all, so they are considering starting a new Discord server.
Matrix has all that these days too
I have not seen a matrix voice channel ever in any of the servers ive seen. Also using element.
Join different servers then? Not sure what to tell you.
I use element and I am in many different matrix servers with voice rooms. I host my own as well, voice is done via livekit which makes connecting via MatrixRTC very easy, and is easy to setup and host.
Those same voice rooms support webcams / video, as well as screen sharing.
So voice is done via a different software not matrix?
