Your GameLoop mic is silent during CODM, BGMI, or Free Fire squad calls. Teammates can't hear you, or you hear no one. This guide covers every real fix — Windows audio routing, GameLoop's internal settings, and game-level voice chat toggles — in order of likelihood.


Why GameLoop Blocks Your Microphone

GameLoop runs as a sandboxed Android VM. Windows treats it like any app competing for audio input — and that's where most mic problems start:

Root CauseFrequency
Windows mic privacy toggle off for desktop appsVery common
Wrong audio device selected in GameLoop settingsCommon
Exclusive mode app (Discord/OBS/Zoom) locked the micCommon
Windows audio driver conflict after Windows UpdateModerate
In-game voice chat disabled in game settingsModerate
GameLoop version bug (specific builds had audio regression)Occasional
Mic muted at hardware level (physical switch/headset button)Often overlooked
USB headset power/USB hub issueOccasional

Before You Start: 2-Minute Pre-Check

  1. Open Voice Recorder (Windows built-in) and speak. Can you record audio? If not — the problem is Windows-level, not GameLoop.
  2. Check your headset's physical mute button. Obvious, but responsible for ~15% of mic reports.
  3. Confirm you're using the right microphone — if you have a webcam, speakers with built-in mic, or a USB headset, Windows may have chosen the wrong default.

Fix 1: Windows Microphone Privacy Settings

This fixes ~40% of cases.

Windows 11/10 has a per-app mic permission toggle that many users don't know exists.

  1. Press Win + IPrivacy & SecurityMicrophone
  2. Toggle Microphone access ON (system-wide)
  3. Toggle Let desktop apps access your microphone ON
  4. Scroll down — verify GameLoop.exe is not individually blocked

Also check:

Windows 10: Settings → Privacy → Microphone → Allow apps to access your microphone → ON, plus "Allow desktop apps" → ON.


Fix 2: Set Correct Input Device in GameLoop

GameLoop has its own audio device selector separate from Windows defaults.

  1. Open GameLoop → top-right gear icon (Settings)
  2. Go to Engine tab → scroll to Audio settings
  3. Under Microphone, open the dropdown
  4. Select your actual microphone (headset, USB mic, etc.) — NOT "Default" if you have multiple devices
  5. Click Save → restart GameLoop

If the dropdown only shows "Default" and your headset isn't listed: check Device Manager for driver issues (see Fix 7).


Fix 3: Close Apps That Use Exclusive Mic Access

Discord, OBS, Zoom, and some recording software grab the microphone in "exclusive mode" — GameLoop cannot share it.

Close these before launching GameLoop:

Then launch GameLoop first, then Discord. If you need Discord voice + game simultaneously: in Discord → Settings → Voice & Video → disable Exclusive mode and set Input Sensitivity to a fixed value.


Fix 4: Check In-Game Voice Chat Settings

Each game has its own voice chat toggle independent of your Windows mic:

CODM (Call of Duty: Mobile)

BGMI / PUBG Mobile

Free Fire

Honor of Kings


Fix 5: Disable Windows Exclusive Mode on the Mic

  1. Right-click the speaker icon in the taskbar → Sounds (Control Panel view)
  2. Click Recording tab
  3. Right-click your microphone → Properties
  4. Go to Advanced tab
  5. Uncheck Allow applications to take exclusive control of this device
  6. Click OK → test in GameLoop

Fix 6: Update or Roll Back Audio Drivers

A Windows Update in late 2025 caused Realtek audio regressions on several laptop models. If your mic stopped working after a Windows Update:

Update path:

  1. Open Device Manager (Win + X → Device Manager)
  2. Expand Sound, video and game controllers
  3. Right-click your audio adapter → Update driver → Search automatically

Rollback path (if it broke after an update):

  1. Same path → Right-click → PropertiesDriver tab
  2. Click Roll Back Driver (only available if a previous driver exists)

For Realtek specifically: download the latest Realtek HD Audio driver from your laptop manufacturer's support page (not Realtek's generic download) for best compatibility.


Fix 7: USB Headset / USB Hub Issues

USB headsets enumerate as a separate audio device. If your mic stops working intermittently:

  1. Plug the headset directly into the PC's USB port (bypass any USB hub)
  2. Try a different USB port (preferably USB 3.0 port on the back panel of a desktop)
  3. Open Device Manager → check for yellow warning triangles under Audio inputs and outputs
  4. Right-click the mic → Uninstall device → unplug → replug to force re-detection

For headsets with separate USB audio controller chips (SteelSeries, Logitech G series, HyperX): install the manufacturer's companion software, which sometimes overrides Windows audio routing.


Fix 8: Reinstall GameLoop Audio Components

If no other fix works, GameLoop's audio module may be corrupted.

  1. Close GameLoop completely
  2. Navigate to C:\Users\[YourUser]\AppData\Local\Tencent\GameLoop (or the install directory)
  3. Delete the Audio subfolder if present
  4. Relaunch GameLoop — it will recreate audio components on startup
  5. If that fails: uninstall GameLoop → reboot → download the latest installer from the official site → reinstall

Note: Reinstalling GameLoop does not delete your game data. Downloaded games are stored in a separate GameDownload folder.

FAQ

Q: My teammates can hear me but I can't hear them. Volume routing issue, not a mic problem. In GameLoop Settings → Audio → set Headphone/Speaker output device to your headset. Also check in-game voice volume slider (separate from music/effects volume).

Q: Mic works in Windows but not in GameLoop specifically. GameLoop isn't seeing it. Go to Fix 2 (select device explicitly) + Fix 5 (disable exclusive mode).

Q: Mic works for 5 minutes then cuts out. USB power management issue. Open Device Manager → Universal Serial Bus controllers → right-click each USB Root Hub → Properties → Power Management → uncheck "Allow the computer to turn off this device to save power."

Q: Push-to-talk key doesn't work in CODM. GameLoop keymapping conflict. In GameLoop's keymapper, check if the push-to-talk key is bound to another GameLoop function. Unbind it from GameLoop and let the game handle it.

Q: Works in CODM but not BGMI. In-game setting difference — go through Fix 4 for BGMI specifically. The voice channel selection in BGMI is particularly easy to miss.
