Severe 20GB Memory Leak in audiodg.exe during Zoom calls on HP OmniBook X Flip (AMD Ryzen 9 AI)

Hello,

I am experiencing a catastrophic memory leak involving audiodg.exe (Windows Audio Device Graph Isolation) exclusively during active calls in the Zoom desktop application. Over the course of a meeting, audiodg.exe continuously hoards RAM, peaking at an astronomical 20 GB of memory usage. This completely starves the system of resources, degrading performance until the audio engine or the application itself crashes.

System Specifications:

  • Laptop: HP OmniBook X Flip 14"
  • Processor: AMD Ryzen 9 AI platform
  • Audio Driver Architecture: ACPI Audio Compositor Device (2025 AMD Driver framework)

Troubleshooting Already Attempted (Did Not Resolve the Issue):

  1. Windows Audio Enhancements: Completely disabled for both the Microphone Array and Speakers via Windows Sound Settings.
  2. Exclusive Mode: Unchecked "Allow applications to take exclusive control of this device" in the legacy Sound Control Panel (mmsys.cpl) for all input/output devices.
  3. Zoom Desktop Settings: Lowered background noise suppression to "Low", changed echo cancellation to "Aggressive", and toggled "Signal processing by Windows audio device drivers" to Off.
  4. Driver Rollbacks: Attempted rolling back system components in Device Manager. Reverting the AMD Audio CoProcessor layer to a generic High Definition Audio driver resulted in a total loss of the sound system. Reverting the ACPI Audio Compositor Device to the generic 2006 Microsoft fallback driver did not stop the memory leak.
  5. Process Isolation: Manually setting CPU affinity for audiodg.exe to core 0/1 slightly mitigates the system impact but does not halt the RAM climb.

Key Diagnostic Finding: The memory leak does not occur when using the Zoom Web Client inside a web browser (Chrome/Edge). The leak is strictly triggered when the 64-bit Zoom desktop client hooks into the ACPI Audio Compositor Device layer to manage hardware-level processing on the Ryzen AI framework.

Given that this occurs on a modern AMD Ryzen AI architecture, this appears to be a structural memory tracking bug between the Windows Audio Graph engine and the AMD ACPI audio routing profile.

Are there any specific registry overrides, hotfixes, or diagnostic steps I can take to resolve this? I am happy to provide Event Viewer or memory dump logs if required.

Thank you.

    Hello Paul Chapman,

    I'm still working on it.

    In the meantime, Let’s try performing an in-place install or in-place upgrade which will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes. If you want to back up your data first, please do so. Once you are done backing up, you can follow the steps in the following guides:

    Hello,

    I have the same issue with audiodg.exe (Windows Audio Device Graph Isolation). When I use the Zoom desktop app with the built-in microphone, audiodg.exe continuously increases its RAM usage, causing my HP OmniBook 7 16 to slow down or freeze.

    When I use an external microphone, the problem disappears.

    Windows and all drivers are fully up to date.

    I found a very recent Microsoft Q&A report describing the same issue on another HP OmniBook.

    Could you please investigate this issue?

    Hello Paul Chapman,

    Welcome to Microsoft Q&A forum.

    Before we proceed further, you said this only happens in active calls of Zoom desktop apps, may I know if you have tried other communication apps like Teams to see if the leak happens?

    I'm waiting for your reply.
