Microsoft has instituted upgrade blocks on Windows 11 version 24H2 for systems utilizing Dirac audio software due to sound output compatibility issues, affecting multiple audio devices. The safeguard specifically pertains to computers with the cridspapo.dll file, linked to this known problem. Reports indicate that users experienced integrated speakers, Bluetooth speakers, and headsets stopping functioning post-upgrade, along with a failure of both first-party and third-party applications to recognize these devices.
Microsoft blocks Windows 11 upgrade for Dirac audio users
In a recent update to the Windows release health dashboard, Microsoft identified the issue and stated, “The incompatibility relates to the software component cridspapo.dll, which is part of these devices’ audio processing software.” This means the safeguard has been applied to avoid further disruption to the user experience until an adequate solution is available from Dirac.
Affected users should refrain from manually updating impacted PCs via the Windows 11 Installation Assistant or the Media Creation Tool until a driver fix becomes available. Once the necessary driver is released by Dirac, Microsoft aims to facilitate its distribution through Windows Update to resolve the ongoing audio issues.
The audio issues are part of a broader set of problems connected to the Windows 11 24H2 release. Another significant compatibility hold has been placed on systems with Auto HDR due to concerns that this feature could cause game freezes or incorrect color rendering during gameplay. Microsoft’s measures focus on preserving the overall update experience by restricting the deployment of version 24H2 to affected devices until these issues are rectified.
For IT administrators, detailed information regarding these safeguard holds can be found in Windows Update for Business reports, accessible under the safeguard ID numbers: 54283088 for Dirac audio issues and 55382406 for Auto HDR problems.
Users operating on Windows Home or Pro editions can verify if a safeguard hold has been placed on their devices by navigating to Start > Settings > Windows Update and selecting “Check for Windows updates.” If a compatibility hold exists, the system will display a message indicating that “Upgrade to Windows 11 is on its way to your device,” accompanied by a “Learn More” link for further details on applicable safeguards.

Known issues in Windows 11 24H2 upgrade
The Windows 11 version 24H2, also referred to as the Windows 11 2024 Update, is now entering broader phases of availability for eligible devices operating on prior versions 22H2 and 23H2. Users should be aware that the rollout is ongoing, and not all devices will receive the update simultaneously. To check for the update, users should select Settings > Windows Update and follow the prompts.
Specific issues like the one related to Dirac Audio’s cridspapo.dll file have heightened concerns regarding sound output. Many users reported complete loss of audio functionality after updating to 24H2, with a notable lack of recognition by various audio-related applications. This entails that until a new driver from Dirac addresses these concerns, Microsoft has prioritized user experience by delaying upgrades on affected devices.
In the ongoing monitoring of this situation, Microsoft continues to track the effectiveness of its safeguard holds and user feedback. As reports on the audio problems continue to surface, investigations are ongoing into the compatibility and integration of third-party audio software with new Windows updates. Microsoft also encourages affected users to report any relevant information about their experiences to aid in the resolution process.
Microsoft remains committed to providing updates on both the Dirac audio compatibility issue and Auto HDR concerns, promising timely communication as new developments arise. As the situation evolves, the company’s partnership with Dirac aims to facilitate swift driver issue fixes, and lifting of the upgrade hold will depend on successful resolutions being implemented on end-user devices.
