Now, this error does not only show on Windows 10 devices. It can also surface on Windows 7 or Windows 8 devices. And it usually comes with this complete message, “The device is being used by another application. Please close any devices that are playing audio to this device and then try again.”

To better understand this error message, let’s first define HDMI.

What Is HDMI?

High-Definition Multimedia Interface or HDMI for short provides a platform or interface between video and audio sources like video display devices and other devices like video monitors, HD televisions, video projectors, digital cameras, Blue-ray players, and camcorders.

Although HDMIs come in different versions that have identical connectors, they each have different capabilities and features. Also, the newer versions are compatible with the older versions, so you may need to use a new one to be able to take advantage of the latest features.

HDMIs are widely used if you want to watch clips or videos on a huge screen. They are also used when connecting multimedia devices to a computer.

While HDMIs play a number of functions, they may also come across errors. Sometimes, users will not hear any audio while using these HDMI cables. Others simply get errors like the “The Device Is Being Used by Another Application” error message.

So, what is this error message and what triggers it to appear?

Solution #3: Roll Back Your Drivers

If you have been using your Windows computer for quite a long time already, then chances are you have probably heard about device drivers. These are pieces of software that allow your Windows operating system to start, use, and control a hardware component. Simply said, they work like translators, enabling your operating system to ask the hardware components connected to your computer to do what you want.

For example, if you try to play a video on YouTube, you press the Play button on the video on YouTube’s website. The browser, which is the application, sends the request to your operating system. Your operating system already knows what to do. Aside from buffering the video using the network card and the graphics card to display the video, it will also ask the sound card to play the audio. Your operating system sends all these requests to the corresponding drivers.

Usually, these drivers are already installed on your operating system. Microsoft has already bundled your operating system with an extensive library of device drivers. So, when you connect a new hardware component to your Windows computer, your operating system can detect it and locate the appropriate driver in the library. If it finds one, then it will be installed, and you will be asked to reboot your computer so you can enable and use the driver.

While these drivers play a critical role in your operating system, they are not without a fault. They too encounter errors. For instance, if you have just recently installed a sound device driver, you may encounter “The Device Is Being Used by Another Application” error. This isn’t uncommon because compatibility issues often cause your system to misbehave.

In this case, rolling back to a previous driver version can solve the issue. Here’s how to do it:

  1. Press and hold the Windows + R keys.
  2. Input devmgmt.msc into the text field and hit Enter.
  3. Double-click on the Sound, video, and game controller section.Device Manager - Sound Video Game Controllers
  4. Find your audio device and double-click on it.
  5. Go to the Driver tab.
  6. Select the Roll Back Driver option and follow the on-screen prompts. Note that if the button is greyed out, then it suggests that it isn’t possible to revert to the previous version.AMD High Definition Audio Device Properties
  7. Restart your computer after reverting to the previous driver version.
  8. Check if the problem has been resolved.

Solution #4: Uninstall the Latest Windows Update

We suggest that you only proceed with this step if you suspect that the issue is caused by a problematic Windows update. If you haven’t installed any update for quite some time, then there is no use in moving forward with this method. Otherwise, if you trust your gut feeling and you suspect that a faulty update has triggered the error, then follow through.

According to some affected users, the update that caused this error is the Windows update KB2962407. So, if you have installed it, just uninstall it and you should be fine.

To uninstall the recent update, here’s what you should do:

  1. Press and hold the Windows + R keys to launch the Run utility.
  2. Type appwiz.cpl into the text field and hit OK.
  3. Click the View Installed Updates link at the upper-left corner of the screen.
  4. Locate the update that you have just installed.
  5. Click on it and select Uninstall.
  6. Restart your computer and check if the problem is fixed.

Solution #5: Install the Windows Native Audio Drivers

If the issue persists, then you may consider using the native audio drivers of Windows. In case you don’t know, Windows has its native drivers. And most of the time, they are compatible with modern hardware components and they work pretty well.

Here’s how to use the native drivers of Windows:

  1. Press and hold the Windows + R keys.
  2. Input devmgmt.msc and hit Enter.
  3. Double-click on the Sound, video and game controller section.

  7. Click the Let me pick from a list of device driver on my computer option.
  8. A list of available drivers will then be displayed. Choose the High Definition Audio Device option.
  9. Hit the Next button.
  10. If prompted, confirm your actions.
  11. Restart your computer and check if the issue persists.

Solution #6: Install the Latest Windows Update

Who knows? They also contain the fix to the “The Device Is Being Used by Another Application” error on Windows 10.

Malware entities also work in different ways and they each have different capabilities. While some of them steal your personal information or slow down your computer, others disrupt your daily operations, affecting your system processes and corrupting your device drivers. This explains why you may be seeing the “The Device Is Being Used by Another Application” error on your computer.

  6. This time, navigate to Protection History.
  7. The Windows Defender tool will identify and automatically get rid of or quarantine any suspicious entity it sees.

Aside from Windows Defender, you can always use a third-party anti-malware suite to ensure your system is free of malware entities. You have plenty of options out there. Just make sure you download one from a trusted source to avoid exposing your computer to more harm.

Once you have removed any malware entity on your device, it is wise to take precautionary measures to keep malware entities at bay.
