Modern Warfare Has No Sound on PC? Fixes to Try

If Modern Warfare has no sound on your PC, first check Windows’ selected output device and the game’s volume mixer, then restart the game. A muted game, incorrect headset or speaker output, audio enhancements, or a temporary game or driver problem can all cause silence; work through the checks below in order.

Start with Windows audio output

Confirm that sound works outside the game. Play a video or a system sound, then check that your headset or speakers are connected, powered on, and not muted using a physical control. If other apps are also silent, the issue is more likely to be Windows, the device, or its connection than Modern Warfare itself.

Open Settings > System > Sound and select the headset or speakers you actually use under Output.
Use the output device’s test option, if available, and raise its volume. Also check the Windows taskbar volume control and any volume wheel or mute button on the headset.
If you use a USB or wireless headset, disconnect and reconnect it. For Bluetooth, confirm that it is connected as an audio device, not merely paired.

Windows may switch outputs when you connect a controller, monitor, docking station, or headset. A game can continue sending audio to the previous device even though you are listening through another one. Choosing the intended output in Windows before launching the game is a useful first test.

Check Modern Warfare’s volume mixer

Windows can mute or lower one application without changing the master volume. With the game open and producing sound, go to Settings > System > Sound > Volume mixer. Find Modern Warfare in the list, make sure its volume is up, and check that its output device is set to the same headset or speakers you selected above. The exact labels can vary slightly across Windows versions.

If the game does not appear in the mixer, return to it and make sure it is running, then check again. Some Windows controls only show active apps. Do not assume the master volume slider rules out an application-level mute: the game’s individual slider may still be at zero.

Review the game’s audio settings

Open Modern Warfare’s audio settings and check the master volume and individual categories, such as effects, dialogue, and music. Raise the relevant sliders and verify that the selected output or mix option, if shown, suits your setup. Menu names and available options can differ between Modern Warfare releases, so use the settings present in your version rather than relying on a guide for another game in the series.

If menus are silent but gameplay is audible, or the reverse, check the corresponding category sliders and test more than one part of the game.
If dialogue is missing but other sounds work, inspect dialogue volume and any voice-chat or communication-device settings.
If sound is distorted, unusually quiet, or missing only on a surround setup, try the game’s standard stereo or headphone mix as a diagnostic.

Changing to stereo is a troubleshooting test, not proof that surround sound is unsupported. A mismatch between the game’s audio mix, Windows’ speaker configuration, and the physical device can make channels seem absent or misplaced.

Restart the game and check updates

Fully close the game, confirm it has exited, and reopen it after selecting the correct Windows output. If the game was launched before a headset was connected or made the default, restarting may make it detect the current device. Restarting Windows can also clear a temporary audio-service or device-detection problem.

If the silence began after an update, check for available updates for the game, Windows, and the audio device’s driver through the normal update tools for your PC. If it started immediately after a driver update, Windows may offer a driver rollback option in Device Manager; availability depends on the device and installed driver. Avoid downloading drivers from unfamiliar sites.

Try device and connection troubleshooting

For USB audio, try another USB port and avoid a hub for the test. For a wired headset, check that the plug is fully seated and that any adapter or splitter is connected correctly. A desktop PC may have separate headphone and microphone jacks; a headset with a combined plug can require a compatible adapter. Test the headset with another device, or test another audio device on the PC, to narrow down which side is failing.

For Bluetooth headphones, Windows can expose different audio modes depending on the device and connection. Disconnect and reconnect the headphones, then reselect them as the output in Sound settings and the volume mixer. If audio works elsewhere but not in the game, focus on the game’s output selection and restart it after reconnecting. Wireless-device behavior varies, so avoid assuming that every headset has the same controls or modes.

When to change enhancements or reinstall

If the basic checks do not help, open the selected output device’s sound properties and temporarily turn off audio enhancements or spatial audio, if those options are present. Test the game, then restore the setting if it makes no difference. Enhancements can interact poorly with some drivers, but disabling them is only a diagnostic step, not a universal fix.

Use the game launcher’s built-in repair or verify option, if available, to check for damaged or missing game files. This is more appropriate when sound disappeared after an interrupted update or other files appear to be missing; it is unlikely to fix a Windows device routed to the wrong output. Reinstalling the game should be a last resort after simpler checks and file verification. It takes longer and may not resolve an operating-system or headset problem.

Frequently Asked Questions

Why does Modern Warfare have no sound when other apps work?
Check the Windows volume mixer for a muted game or a different app-specific output device. Then inspect the game’s volume and audio settings, and restart it after selecting the correct Windows output.

Why can I hear the game but not voice chat?
Voice chat may use a separate communication device or volume control. Check the game’s voice-chat settings, Windows output and communication-device selection, and the headset’s mute control.

Should I reinstall Modern Warfare to fix the sound?
Not as a first step. Check device selection, mixer levels, game settings, and updates first. If the problem began after a game update, use the launcher’s file-repair option before considering a reinstall.

Why does sound stop when I connect a controller or headset?
Windows may switch its default output when a new audio device appears. Select the intended device again in Sound settings and the volume mixer, then restart the game if it still uses the old output.

What if nothing on my PC has sound?
Check the physical connection, mute controls, Windows output selection, and volume. If the device still fails with other apps, troubleshoot Windows or the audio device before changing game settings.
