Whenever a process or program starts consuming extensive resources, it’s bound to downgrade the system’s performance and lead to lagging issues.

This will cause the apps to crash and even lead to a complete shutdown in the worst case. Do go through our guide on how to speed up your Windows 11 PC and prevent that from happening.

If the audiodg.exe is using a high CPU, rest assured the problem is easily fixable. But before we head to that, let’s first understand what the process is all about.

Why is the audiodg.exe process consuming high CPU?

The audiodg.exe or the Windows Audio Device Graph Isolation process plays a critical role in audio enhancement, apart from digital signal processing.

It’s isolated from the Windows Audio service to allow hardware producers to use their own enhancement service. Isolating reduces the likelihood of conflicts and prevents the OS from crashing.audiodg.exe process

The process is configured to run in the background for the best audio output. However, it’s found to be consuming high CPU values at times. This could be due to one or more of the following reasons:

  • Running an outdated version of the sound card driver
  • Enhanced audio effects
  • Malfunctioning external peripherals

After understanding the underlying causes, you are in a far better position to start troubleshooting the audiodg.exe high CPU error. Let’s now walk you through the most effective fixes.

What can I do if Windows 11’s audiodg.exe is using a high CPU?

1. Remove external peripherals

Your primary approach when dealing with high CPU usage by audiodg.exe is to remove any external microphones or headsets. After disconnecting, verify if the resource consumption changes.

If it does, reconnect the peripheral and check the effects. In case the CPU usage continues to be under normal levels, the error is fixed.

But if it spikes again, the issue most likely lies with the device or its configured settings. In which case, try the methods listed below and if they don’t work, replace the device itself. Also, check our curated list of headphones, in case you plan to purchase one.

2. Update drivers (both sound card and devices)

  1. Press Windows + S to launch the Search menu. Enter Device Manager in the text field at the top, and click on the relevant search result that appears.Launch Device Manager to fix audiodg.exe high CPU

Running an outdated driver is also known to cause high CPU usage by the audiodg.exe process. This can be resolved by updating the driver to the latest version. Though Windows takes care of the updates, there’s no harm in checking for it manually.

The Device Manager method listed above only looks for newer driver versions on the computer, thus acting as an offline update.

If you don’t remember downloading it or Windows is unable to find one, you can always look for the latest driver version in Windows Update or download it from the manufacturer’s website.

Similarly, update the drivers for the external audio devices connected to the PC. In case that sounds like too much trouble, you can always go with a third-party app. We recommend using DriverFix, a dedicated tool that will scan the web for updates and keep the installed drivers up-to-date.
