GameLoop Sound Not Working Fix 2026: Complete Audio Troubleshooting Guide

---

The Quick Answer

If GameLoop has no sound: right-click your Windows speaker icon → Open Sound settings → App volume and device preferences, find GameLoop, and ensure its output device is set to your speakers or headset (not "Default" if Default is pointing at the wrong device). Also check that GameLoop is not muted in Windows Volume Mixer.

If that doesn't fix it, work through the full guide below — audio problems in GameLoop have 7 distinct causes, each with a different fix.

Diagnosing Your Sound Problem

Before applying any fix, identify which type of audio issue you have:

---

Fix 1: Check Windows Volume Mixer (Most Common Fix)

Windows Volume Mixer controls each app's volume independently. GameLoop may be muted here without you knowing.

Steps:

1. Right-click the speaker icon in the taskbar (bottom-right)
2. Select "Open Volume mixer"
3. Look for GameLoop in the list of applications
4. If the slider is at 0 or the speaker icon shows muted — drag it up to 100 and click the mute icon to unmute
5. Also check that your main output device volume is not at 0

Quick test: Open Windows Sound Recorder, record 5 seconds, play it back. If you hear audio through your intended device, Windows audio is working and the issue is GameLoop-specific.

Fix 2: Set the Correct Output Device in App Volume Preferences

GameLoop can output to a different device than your OS default, which causes a "no sound" situation when your headset is plugged in.

Steps:

1. Press Win + I → System → Sound
2. Scroll down to "Advanced sound options" → click "App volume and device preferences"
3. Find GameLoop in the list (it may appear as "GameLoop" or the specific game name)
4. Under Output, change the dropdown from "Default" to your actual output device (headset, speakers, etc.)
5. Restart GameLoop

Tip: If GameLoop isn't in the list, launch it and start a game first, then come back to this settings page — apps only appear here while running.

---

Fix 3: Restart the Windows Audio Service

Windows' audio engine can crash or freeze, especially after sleep/wake cycles. Restarting the audio service forces a clean reset.

Steps:

1. Press Win + R, type services.msc, press Enter
2. Scroll to "Windows Audio"
3. Right-click → Restart
4. Also restart "Windows Audio Endpoint Builder" the same way
5. Relaunch GameLoop

Alternative (faster): Open Command Prompt as Administrator and run:

net stop audiosrv && net start audiosrv

Fix 4: Update or Reinstall Your Audio Driver

Outdated or corrupted audio drivers are a top cause of GameLoop sound issues, especially after Windows Updates.

Steps:

1. Press Win + X → Device Manager
2. Expand "Sound, video and game controllers"
3. Right-click your audio device (e.g., "Realtek High Definition Audio" or "NVIDIA High Definition Audio")
4. Select "Update driver" → "Search automatically for drivers"

If the update doesn't help — try reinstalling:

1. In Device Manager, right-click your audio device → "Uninstall device"
2. Check "Delete the driver software for this device"
3. Restart your PC
4. Windows will automatically reinstall the default driver on next boot
5. Then download the latest driver from your motherboard manufacturer's site (Realtek, ASUS, MSI, etc.)

Fix 5: Fix Audio Crackling / Popping (Sample Rate Mismatch)

Crackling and popping sounds in GameLoop are almost always caused by a sample rate conflict between GameLoop's audio engine (often 44,100 Hz) and Windows' audio format setting.

Steps:

1. Right-click the speaker icon → Open Sound settings
2. Click "Sound Control Panel" (right side) → Playback tab
3. Right-click your active output device → Properties
4. Go to Advanced tab
5. Under "Default Format", try:

• "24 bit, 48000 Hz (Studio Quality)" — best for most setups
• If crackling continues, try "16 bit, 44100 Hz (CD Quality)"

1. Click Apply → test GameLoop audio

Also check Exclusive Mode: On the same Advanced tab, uncheck:

• "Allow applications to take exclusive control of this device"

This prevents GameLoop from locking the audio device away from Windows and other apps.

Fix 6: Mic / Chat Audio Fix (Voice Chat Not Working)

This is a separate problem from game audio. If you can hear game sounds but teammates can't hear you — or you can't hear them — follow these steps:

Check GameLoop microphone permissions:

1. In GameLoop, go to Settings (⚙) → Privacy
2. Find Microphone → set to Allow

Check Windows microphone permissions:

1. Win + I → Privacy & Security → Microphone
2. Enable "Allow apps to access your microphone"
3. Scroll down and ensure GameLoop is toggled On

Set the correct input device:

1. Right-click speaker icon → Open Sound settings → Input
2. Confirm your microphone is set as the default input
3. In App volume and device preferences, set GameLoop's Input to your microphone

Test: Use the Windows Voice Recorder to confirm the mic records correctly before blaming GameLoop.

Fix 7: GameLoop Sound Engine Reset (For Persistent Issues)

GameLoop caches audio configuration data. A corrupted cache can prevent audio from working even when drivers and Windows settings are correct.

Method A — Clear GameLoop audio cache:

1. Close GameLoop completely (check Task Manager to ensure all processes ended)
2. Navigate to: C:\Users\[YourName]\AppData\Local\Tencent\GameLoop
3. Find folder named "audio_cache" or "cache" — delete it
4. Relaunch GameLoop

Method B — Reset GameLoop audio settings to default:

1. Open GameLoop → Settings (⚙) → Audio
2. If there's a "Reset to Default" or "Restore" option — click it
3. Set output device explicitly to your preferred audio device
4. Apply and relaunch

Method C — Repair GameLoop installation:

1. Open Windows Settings → Apps → Apps & features
2. Find GameLoop → click Modify or Repair (if available)
3. Follow the repair wizard
4. This preserves your games and data while fixing corrupted GameLoop files

Fix 8: No Sound in a Specific Game (Other Games Work Fine)

If GameLoop plays audio in one game but not another, the problem is game-level, not GameLoop-level.

Typical cause: The game's audio settings were changed, or the game lost its audio configuration.

Steps:

1. Open the problem game within GameLoop
2. Go to the game's Settings → Audio/Sound
3. Ensure:

• Master Volume: Not at 0
• Sound effects: Enabled
• Mute: Off

1. For CODM specifically: Settings → Audio → "Enable Game Sounds": On
2. For PUBG Mobile: Settings → Audio → Master Volume slider up

If the game has no in-game audio settings: Clear the game data in GameLoop's Android environment:

1. In GameLoop, open the Android settings (Settings cog within GameLoop → Android Settings)
2. Apps → find your game → Storage → Clear Data
3. Relaunch the game (you'll need to download game data again)

Fix 9: GameLoop Audio After Windows Update

Windows Updates sometimes reset audio settings or change driver versions. If GameLoop audio stopped after a Windows Update:

1. Roll back the audio driver:

• Device Manager → Sound devices → right-click audio device → Properties → Driver tab → "Roll Back Driver"
• If greyed out, the previous driver wasn't saved; skip to step 2

1. Re-run Windows audio troubleshooter:

• Win + I → System → Troubleshoot → Other troubleshooters → Playing Audio → Run
• Let Windows auto-fix any detected issues

1. Check Spatial Sound settings:

• Right-click speaker icon → Spatial sound
• If it's set to "Windows Sonic" or "Dolby Atmos" — try switching to "Off" and test GameLoop

Quick Diagnostic Checklist

• [ ] Are audio drivers up to date? (Device Manager → Sound → Update driver)
• [ ] Is Windows Audio Service running? (Services.msc → Windows Audio → Status: Running)
• [ ] Is the sample rate set correctly? (Sound Control Panel → Playback → Properties → Advanced → 48000 Hz)
• [ ] Does sound work in other apps? (If yes, problem is GameLoop-specific → Fix 7)

Still No Sound? Try This

If none of the above fixes work, the issue is likely one of:

1. Conflicting audio software — Nahimic, SteelSeries Engine, Sonic Studio, or other "gaming audio" suites can intercept and block GameLoop's audio. Temporarily disable them and test.

1. HDMI or DisplayPort audio conflict — If you connect via HDMI/DP, Windows may default audio output to your monitor instead of your headset. Check Device Manager → Sound → disable the HDMI audio adapter.

1. GameLoop version too old — Some audio bugs were fixed in newer GameLoop versions. Go to the GameLoop official site and download the latest installer. Run it over your existing installation — your games are preserved.

1. Complete reinstall — As a last resort, uninstall GameLoop, delete C:\Users\[YourName]\AppData\Local\Tencent\GameLoop and C:\Users\[YourName]\AppData\Roaming\Tencent\GameLoop, then reinstall fresh.
