Voice on
Linux
The Cult Voice is a Mumble plugin. It makes other players sound like they are where they actually are in the game — quieter with distance, and to your left or right. This page is the whole setup, start to finish. It takes about two minutes.
Before you start
You need Mumble 1.4 or newer. Plugins did not exist before 1.4, so on older Mumble the plugin simply cannot appear — there is no setting to find. The version in the Mint and Ubuntu software manager is often 1.3, which will not work.
Check what you have:
mumble --version
If that says 1.3 or lower, install a current Mumble instead:
flatpak install flathub info.mumble.Mumble
You also need curl and xdg-open, which the plugin uses once to open the approval page in your browser. Most desktops already have both:
sudo apt install curl xdg-utils
Install
Quit it completely first. The installer will stop and tell you if Mumble is still running, because a plugin cannot be replaced underneath a running client.
curl -L -o the-cult-voice.sh https://islecult.com/downloads/voice/installer/linux sh the-cult-voice.sh
Do not pipe it into a shell. curl ... | sh will not work: the installer carries the plugin inside itself and reads its own file to unpack it, so it has to be saved to disk first.
Do not use sudo. The plugin belongs in your own Mumble folder, not root's. The installer refuses to run as root for exactly that reason.
It prints every folder it installed into. It finds the normal, Flatpak and Snap versions of Mumble by itself.
Start Mumble and go to Configure → Settings → Plugins.
Tick The Cult Voice, then press Apply and OK. Untick any other Isle proximity plugin — two of them will fight over the same voices.
Go to Server → Connect → Add New and fill in:
Label: The Cult Address: mumble.islecult.com Port: 64738 Username: anything you like
Connect to The Cult. A page opens in your browser — click Link proximity voice and you are done. You will not be asked again unless you replace Mumble's certificate.
If the plugin is not listed
Almost always this means the Mumble you opened is a different install from the one the plugin went into — a lot of people have both the Flatpak and the normal version without realising.
Point the installer straight at the one you actually use. For Flatpak:
sh the-cult-voice.sh --dir ~/.var/app/info.mumble.Mumble/data/Mumble/Mumble/Plugins
For Snap:
sh the-cult-voice.sh --dir ~/snap/mumble/current/.local/share/Mumble/Mumble/Plugins
The normal install reads from ~/.local/share/Mumble/Mumble/Plugins. The other thing worth re-checking is the Mumble version above — 1.3 has no Plugins page at all.
Other problems
- No browser page appears. Install
curlandxdg-utils. If the browser still does not open, the approval link is written to the plugin's log and you can paste it in yourself. - Nobody can be heard. Check Mumble is connected, the plugin is ticked, and that another linked player is actually near you in game. The plugin mutes anyone the server has not placed near you — that is deliberate, so a network fault can never turn proximity voice into a global channel.
- You want to see what it is doing. The log lives beside the plugin:
tail -f ~/.local/share/Mumble/Mumble/Plugins/the_cult_voice.log
received UPDATE2 with 0 speakersis healthy when you are alone or nobody nearby is talking. - You want it gone.
sh the-cult-voice.sh --uninstallremoves it from every folder it installed into. Your settings backups are left alone.
