  2. Check if there’s a green tick on your desired playback device. If not, select your device and click Set Default. Then click OK.
  3. Open Modern Warfare and see if your problem has gone away. If the problem is still there, repeat step 1 and select your playback device, then click Properties.
  4. Navigate to the Advanced tab. Under the Default Format section, select a different sample rate and bit depth, then click Test. Repeat this process until you find a format that works with your device. Then click OK.

Fix 4: Update your audio driver

Among the many cases of sound issues, one common scenario is that your speakers are loud and clear while your headset seems broken. In this case, 9 times out of 10 your PC is missing a correct audio driver for your headphone. In addition, a faulty or outdated audio driver can also be the culprit of your sound issues.

More often than not you can fix the audio issue by updating your driver. And there are mainly 2 ways you can do that: manually or automatically.

Option 1: Update your audio driver manually

To update your audio driver manually, go to your motherboard manufacturer’s website and search for your model. Drivers are usually available at the Support or Download page. Choose only the installer that’s compatible with your operating system. And don’t forget to reboot your PC after updating the driver.

If you’re using a bluetooth headset, you’ll need to install and enable the bluetooth driver as well.

Option 2: Update your audio driver automatically (Recommended)

If you don’t have the time, patience or computer skills to update the audio driver manually, you can do it automatically with Driver Easy.

  1. Download and install Driver Easy.
  2. Run Driver Easy, then click Scan Now. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.
    (This requires the Pro version – you’ll be prompted to upgrade when you click Update All. If you don’t want to pay for the Pro version, you can still download and install all the drivers you need with the free version; you just have to download them one at a time, and manually install them, the normal Windows way.)
The Pro version of Driver Easy comes with full technical support. If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

Once you’ve updated your audio driver, restart your computer and see if it fixes your problem.

If updating audio driver doesn’t do the trick for you, please take a look at the next fix.

Fix 5: Install all the Windows updates

There’re many reports that installing system updates fixes the audio issue on Windows, so this could be a potential solution to your sound issue with Modern Warfare.

And it’s quite easy to update too:

  1. On your keyboard, press the Windows logo key and R at the same time to invoke the Run box. Type or paste control /name Microsoft.WindowsUpdate and hit Enter.
  2. Click Check for updates. It’ll take some time for Windows to search and install system updates.
  3. Once you’ve installed the updates, restart your computer for it to take full effect.

To install all the system updates, you might need to repeat these steps several times until it prompts that “you’re up to date” when you click Check for updates.

You can now open Modern Warfare and check the in-game audio.

If this method doesn’t work for you, please move on to the next one below.

Fix 6: Close conflicting software

Some players reported that they managed to get the sound back by closing programs that have audio output. You can try this method by closing apps such as Discord, Skype and Chrome, as they might affect the in-game audio.

Fix 7: Change your audio channel

In some cases, output devices with some high-end features (e.g. 5.1 surround sound) might not work so well on your system, so you’ll need to change your audio channel for the audio output. This solution also apply to the case where players have only cinematic music and no sound effects.

Here’s how to do it:

  1. On the lower-right corner of your desktop, right-click the volume icon and select Sound.
  2. Navigate to the Playback tab. Select your default playback device and click Configure.
  3. For Audio channels, select Stereo and click Next.
  4. Check the box next to Front left and right. Then click Next.
  5. Click Finish to save the changes.
