  2. audiodg.exe using a lot of RAM and CPU

    Hi,

    Thank you for posting your query in Microsoft Community.

    I understand the inconvenience you are facing currently.

    I would appreciate if you can provide us the following information to help us understand the issue better.

    • Have you tried any troubleshooting steps to resolve this issue?
    • Do you get any error code or error message while startup?
    • Have you made any changes to the computer prior to this issue?
    Audiodg.exe [Windows Audio Device Graph Isolation] file hosts the audio engine for the operating system. So, this file is utilized for all the
    audio processing and Digital Signal Processing (DSP). Vendors are able to install their own DSP and audio effects into the audio pipeline, which are then processed by audiodg.exe.

    In order to fix the high CPU usage, disable the audio enhancements processed by the audiodg.exe file. To disable the audio enhancements, try the following steps:

    • Right-click the speaker icon in the right-hand notification area on the taskbar.
    • Select Playback Devices from the menu. A list of devices should appear on the screen.
    • Double-click the device that has a green checkmark. The properties windows for that device should open.
    • Click the Enhancements tab at the top.
    • From the list of enhancements, uncheck all of them, or click the Disable all enhancements
      checkbox.
    • Click the OK button to save your changes and close the window.
    • Click OK to close the Playback Devices window.
    I also suggest you use Resource Monitor to monitor CPU usage.

    Resource Monitor is a tool that you can use to monitor the usage of CPU, hard disk, network, and memory in real time.

    You can use the Performance tab in Task Manager to see how your computer's CPU is being used by Windows and other programs running on your computer.

    Hope the information helps. Please let us know if the issue persist and we will be happy to assist you further.
