GameLoop Mic Not Working — Voice Chat Fix Guide
Voice chat in GameLoop involves Windows privacy settings, a default-device distinction most people miss, and per-game settings that sit entirely outside the emulator. The fix is almost never reinstalling GameLoop.
When a microphone stops working inside GameLoop, the fault usually sits outside the emulator entirely — in Windows privacy settings, the wrong default device, or a per-game voice chat toggle. Reinstalling GameLoop does not touch any of these.
This guide covers the actual causes in order of how often they appear.
Windows microphone privacy
Windows 10 and 11 have a microphone privacy toggle that controls whether applications can access the recording device. If GameLoop was installed before you connected your headset, or if a Windows update reset permissions, this toggle may be off.
Go to Settings → Privacy & Security → Microphone. Make sure both "Microphone access" and "Let desktop apps access your microphone" are enabled. The second toggle is specifically for applications like GameLoop that are not Microsoft Store apps. After changing it, close GameLoop completely (right-click the tray icon, Exit) and restart it.
Default communication device
Windows distinguishes between two device roles: Default Device and Default Communication Device. Applications that handle voice calls — including the voice chat systems inside mobile games — use the communication device, not the default playback device. These can be set to different endpoints without any visible indication that they differ.
Open Sound settings → More sound settings → Recording tab. Right-click your microphone and check whether it is set as the Default Communication Device separately from Default Device. Set it to both. If your headset has a dedicated microphone entry and a combined entry in the list, the combined one (usually labelled "Headset Microphone") is the one voice chat applications use. The stereo entry ("Headphones Microphone") is for audio recording, not real-time communication.
GameLoop's own audio device selection
GameLoop carries its own audio routing settings independent of Windows defaults. If the emulator's microphone input is pointed at a device you are not using — or a device that was disconnected — Windows-side changes will not fix it.
In GameLoop, open Settings → Sound (accessible from the gear icon in the toolbar). Confirm the microphone device shown there matches what you are actually using. If the list is empty or shows a stale entry, disconnect and reconnect your headset, then open GameLoop settings again to refresh the device list.
Bluetooth headsets
Bluetooth headsets present two separate audio profiles to Windows. The A2DP profile provides high-quality stereo audio for listening, but it does not include a microphone. The HSP/HFP profile adds microphone capability at lower audio quality. Windows switches between them automatically, but the switch sometimes does not happen cleanly, leaving you in a state where you hear audio but your mic is not active.
Two things help: first, connect the headset before opening GameLoop — the emulator enumerates audio devices on startup, and a headset connected after the fact may not be picked up. Second, if the mic is not active during a game session, open your Bluetooth device properties in Windows and confirm which profile is currently connected. Switching the headset off and back on usually forces Windows to re-negotiate the profile.
Audio quality will be noticeably lower when the mic is active on a Bluetooth headset. That is normal — it is the hardware limitation of the HFP profile, not a GameLoop problem.
Exclusive mode conflict
Another application may have taken exclusive ownership of the microphone device before GameLoop started. Discord, Windows Gaming Bar, and voice-processing software (like RTX Voice or Nvidia Broadcast) commonly hold the mic in exclusive mode.
Open the recording device's Properties in Sound settings, go to the Advanced tab, and uncheck "Allow applications to take exclusive control of this device." This lets multiple applications share the mic simultaneously. Alternatively, close other applications that use a microphone before starting GameLoop and the game.
Per-game voice chat settings
Each game controls its own voice chat independently of GameLoop. This is the second most commonly missed item after Windows privacy.
In Call of Duty: Mobile: open the in-game Settings, go to the Audio tab, and check that Voice Chat is enabled and the input device matches your microphone. The voice mode defaults to push-to-talk in some regions, which means you need to press a button to speak. On GameLoop, that button is part of the on-screen HUD and may not be mapped to a keyboard key by default. Map it explicitly in the GameLoop keyboard editor, or switch voice mode to Open Mic in the game settings.
In PUBG Mobile: Settings → Audio → Voice Chat. Check the input device and verify the mode is not set to push-to-talk without a mapped key.
Other games follow the same pattern: find the voice or audio section in the game's own settings before assuming the problem is in GameLoop.
Sample rate mismatch
Windows records at the sample rate configured for the device. If the rate is set to something uncommon — 192 kHz is a frequent culprit on gaming headsets that advertise high-resolution audio — some games refuse to accept the stream and silently drop the mic input.
In Sound settings → Recording, right-click the microphone, open Properties, go to the Advanced tab, and change the Default Format to 2 channel, 16 bit, 48000 Hz. This is the rate most voice chat systems expect. After changing it, close GameLoop and restart.
Testing the microphone outside GameLoop
Before trying anything else, confirm the microphone works at all. The Windows Settings app includes a Microphone test on the same page as privacy settings. Record a short clip in Voice Recorder or speak into the browser's microphone test at any web-based tester. If the mic does not respond there either, the problem is hardware or driver-level — GameLoop is not involved.
If the mic works outside GameLoop but not inside, work through the sections above starting with the privacy settings and default communication device.
Reinstalling GameLoop
Reinstalling the emulator does not change Windows privacy settings, default recording devices, or per-game voice settings. It also does not update audio drivers. The only scenario where reinstalling helps is a corrupted GameLoop audio module, which is rare and usually accompanied by other unusual behavior. Exhaust the steps above before going there.
