How to Configure Mumble Voice Chat in FiveM

Learn how to set up and optimize high-quality in-game voice using FiveM’s built-in Mumble system with PMA-Voice.

Crystal Clear Spatial Communication

FiveM includes a native Mumble-based voice system, designed to deliver:

• Low-latency voice communication
• 3D positional audio (players sound closer/further based on distance)
• Radio and proximity-based communication
• Full synchronization with in-game movement

Using Mumble instead of external tools (like Discord or TeamSpeak) allows for a fully immersive roleplay experience, where voice behaves exactly like real-world sound.

Recommended Setup: PMA-Voice

While FiveM includes native voice, the PMA-Voice resource is the industry standard for:

• Stability
• Advanced features (radio channels, call systems)
• Better control over proximity and audio behavior

If you're serious about quality and scalability, using PMA-Voice is not optional.

Server Configuration (Required)

To enable and properly configure Mumble, add the following lines to your server.cfg.

⚠️ These must be placed before starting your voice resource (e.g., ensure pma-voice).

Core Voice Settings

# Enable Native Audio (Required)
setr voice_useNativeAudio true

This activates FiveM’s built-in Mumble system.

Proximity & Audio Logic

# Only transmit voice within proximity range
setr voice_useSendingRangeOnly true

# Enable submix for radio effects and filtering
setr voice_enableSubmix 1

These settings ensure:

• Players only hear others within range
• Radio audio sounds distinct from proximity chat

Default Keybinds & Volume

# Key to cycle voice range (whisper / normal / shout)
setr voice_defaultCycle "F11"

# Default voice volume (0.0 - 1.0)
setr voice_defaultVolume 0.4

You can adjust these based on your server’s UX preferences.

Resource Initialization

Make sure PMA-Voice is started in your server.cfg:

ensure pma-voice

Recommended load order:

• Dependencies first
• Voice system early (before gameplay scripts)

In-Game Features Enabled

With proper configuration, players will have:

• Proximity voice (distance-based audio)
• Voice range cycling (whisper, normal, shout)
• Radio communication systems (if configured)
• Directional audio (left/right positioning)

Troubleshooting Voice Issues

If players report voice problems, don’t guess — isolate the issue quickly using this checklist.

1. Output Device Verification

Have the player check:

GTA V Settings → Voice Chat

• Output Device = correct headphones/speakers
• Input Device = correct microphone

Wrong device = no audio, even if everything else is correct.

2. Client-Side Issues

Common fixes:

• Restart FiveM
• Clear client cache
• Reconnect to server

If only one player is affected, it’s almost always client-side.

3. Submix / Audio Conflicts

If players:

• Hear distorted audio
• Can’t hear radio properly

→ Verify:

setr voice_enableSubmix 1

Disabling or misconfiguring this breaks radio filtering.

4. Resource Conflicts (Critical)

If voice is:

• Randomly cutting out
• Not working for some players
• Completely broken

You likely have conflicting voice scripts.

Remove Legacy Voice Systems

If you are upgrading or migrating your server, you must remove old voice resources.

Common conflicts include:

• esx_voice
• vdk_voice
• mumble-voip

⚠️ Running multiple voice systems will break everything:

• Microphones stop working
• Players can’t hear each other
• Voice becomes unstable

Best Practices

Keep Voice System Clean

Only run:

• pma-voice
• Native Mumble (enabled via config)

Nothing else.

Test After Every Change

After modifying voice settings:

1. Restart server
2. Join with 2+ players
3. Test proximity + radio

Don’t Overcomplicate Early

Start with:

• Default PMA-Voice setup
• Basic proximity chat

Then expand into:

• Radios
• Calls
• Voice channels

Common Mistakes to Avoid

• Placing voice config after resource start
• Running multiple voice systems
• Ignoring client audio settings
• Assuming voice issues are server-side (they often aren’t)

Proper voice setup is one of the highest-impact improvements you can make to your server. If it’s broken, players leave. If it’s flawless, it massively improves immersion and retention.
