About this project

What does e4mc Voice Compatibility add?

E4MC Voice Compatibility Title

Makes Simple Voice Chat work for players who join your world through e4mc.

The problem

e4mc opens your LAN world to anyone on the internet by tunneling the Minecraft connection through a relay. Simple Voice Chat sends audio over a separate UDP port, which e4mc doesn't forward. Your friends can join and play, but their voice chat stays disconnected.

The fix

This mod sends voice through the Minecraft connection itself, so it goes through the e4mc tunnel like the rest of the game.

  • Works with both e4mc connection modes: the relay (*.e4mc.link address) and Dialtone.
  • The host and players on your local network keep using regular voice chat. Nothing changes for them.
  • A player who joins through e4mc without this mod can still play, and gets a chat message explaining why voice chat doesn't work for them.
  • No configuration needed.

Installation

Download the file that matches your Minecraft version, and install it on the host and every player, alongside its dependencies.

Then open your world to LAN as usual, share the e4mc address, and voice chat connects on its own.

Requirements

Available for Minecraft 1.20.5 to 26.3, on Fabric.

Good to know

  • Latency: voice through e4mc may lag a bit more than direct voice chat on an unstable connection. The Minecraft connection resends lost packets instead of skipping them.
  • Bandwidth: voice traffic goes through the e4mc relay along with the game.
  • Both sides need the mod. A player with only Simple Voice Chat can't use voice through e4mc.
  • Voice stays encrypted by Simple Voice Chat. This mod only forwards it.

Troubleshooting

If voice chat doesn't connect, check logs/latest.log.

  • On the host: look for Tunneling voice chat of <player>. If you see joined through e4mc ... without e4mc Voice Compat instead, that player is missing the mod.
  • On the joining player's side: look for Voice chat connection tunneled through e4mc.

When reporting an issue, please include both logs: the host's and the joining player's.
