CODM Voice Chat Not Working on GameLoop PC — Fix Guide

Call of Duty: Mobile's voice chat passes through more layers on GameLoop than on a phone: the Android microphone API inside the emulator, GameLoop's bridge between that API and your Windows audio devices, the Windows microphone permissions stack, and finally the CODM in-game voice settings. When voice is broken, the fault is almost always in the Windows layer — not in CODM itself.

The first thing to check: Windows microphone privacy

Windows has a global microphone permission toggle that blocks all applications from recording unless explicitly allowed. GameLoop runs as a desktop application, so it falls under the Desktop apps bucket — but Windows also requires apps to be individually permitted when the global toggle is on.

Open Settings → Privacy and security → Microphone. Confirm that "Microphone access" is on at the top, then scroll down to "Let desktop apps access your microphone" and make sure it is also on. If either toggle was off, restart GameLoop completely (right-click the system tray icon, choose Exit) before testing again. Windows caches the permission state at launch.

GameLoop's own microphone setting

GameLoop presents a virtual Android microphone to the game. If Windows is routing input from the wrong physical device, the virtual microphone still appears to work — but feeds silence into the game.

Open GameLoop's settings (the gear icon inside the emulator, not the Windows launcher). Navigate to Audio. The microphone input should be set to the same device you use for everything else. If it is set to "Default" and your Windows default device is wrong, fixing the Windows default device resolves this without touching the GameLoop setting.

After changing the device, fully exit and restart GameLoop. Changes to audio device routing do not apply to a running session.

CODM in-game voice settings

Even when the microphone reaches the game, CODM can mute itself at the application level.

Inside CODM, open Audio Settings (found in the main Settings menu and also accessible during a match via the top-right gear). Check:

• Voice Chat: must be set to On. A separate toggle exists for multiplayer and for Battle Royale.
• Voice Chat Mode: Open Mic transmits automatically. Push to Talk requires you to hold a key — on GameLoop the default is usually F1, but it can be unbound if the keymapping was reset. Check Keymapping settings and confirm Push to Talk has a key assigned.
• Microphone Volume: a slider separate from the speaker volume. If it was accidentally dragged to zero the game receives no input regardless of Windows or GameLoop settings.
• Channel: Voice chat has Team and Proximity options. If you are in a squad on Team channel, players outside your squad will not hear you and you will not hear them, even if everything is working correctly.

One-directional voice: you can hear but cannot be heard

This specific pattern — you hear teammates but they cannot hear you — points to the microphone path, not the speaker path. Everything above applies, but start with Windows permissions, then GameLoop's audio input device, then CODM's microphone volume and push-to-talk binding.

The most common cause is the Windows exclusive mode conflict. Open your microphone device properties in Windows Sound Settings → Recording, go to the Advanced tab, and uncheck "Allow applications to take exclusive control of this device." Communications apps (Discord, TeamSpeak) often grab exclusive access and leave CODM's path to the emulator without a working input source.

The reverse: teammates cannot hear each other but you can hear all of them

If you can hear voice but your own voice works fine elsewhere (Discord, system recorder) and only fails in CODM, the in-game voice settings are the most likely cause. Re-check the in-game channel setting. In Battle Royale proximity voice, players outside a certain radius are intentionally inaudible — this is expected behaviour, not a bug.

Microphone appears to work in Windows but still silent in game

GameLoop's Android layer can cache audio device assignments from a previous session. The reliable fix:

1. Exit GameLoop fully from the system tray.
2. Open Windows Device Manager, find the audio section, right-click your microphone, and Disable then re-enable it.
3. Restart GameLoop.

This forces both Windows and the emulator to re-enumerate the device from scratch.

If the problem started after a Windows Update, check the microphone driver date in Device Manager. Windows Update occasionally replaces a vendor driver with a generic one and the symptom is exactly this — other applications work, CODM voice does not. Rolling back the driver in Properties → Driver → Roll Back Driver typically resolves it in one step.

Quick checklist

• Windows Settings → Privacy → Microphone → both toggles on ✓
• GameLoop audio settings → microphone set to your active input device ✓
• GameLoop fully restarted after any settings change ✓
• CODM Audio Settings → Voice Chat on, Microphone Volume above zero ✓
• Push to Talk key bound in Keymapping if that mode is selected ✓
• Windows Recording devices → exclusive mode unchecked ✓
• Voice Chat channel set to the correct option (Team vs Proximity) ✓
