Microsoft has implemented a precautionary measure regarding the Windows 11 24H2 upgrade, specifically targeting systems that utilize Dirac audio enhancement software. This decision stems from identified compatibility issues that disrupt sound output on affected devices.
Details of the Compatibility Issue
The problem is linked to the software component cridspapo.dll, integral to the audio processing capabilities of certain devices. According to Microsoft’s recent update on the Windows release health dashboard, users have reported that after upgrading to Windows 11, version 24H2, their integrated speakers, Bluetooth speakers, and headsets ceased functioning. Additionally, both first-party and third-party applications failed to recognize these audio devices.
To mitigate the impact of this issue, Microsoft has placed a safeguard hold on Windows devices equipped with Dirac audio software. IT administrators can reference this issue under safeguard ID 54283088 in Windows Update for Business reports.
Guidance for Affected Users
Microsoft advises users experiencing these audio disruptions not to manually upgrade their devices using the Windows 11 Installation Assistant or the Media Creation Tool until Dirac releases a fix for their audio driver. The company has assured users that once the manufacturer provides a solution, Microsoft will collaborate to distribute the updated driver through Windows Update, effectively resolving the audio concerns.
The safeguard hold preventing the update to version 24H2 will remain in place until the issue is rectified on users’ devices. For those utilizing Windows Home or Pro editions, checking for safeguard holds is straightforward: navigate to Start > Settings > Windows Update and select Check for Windows updates.
If a compatibility hold is in effect, users will see a message indicating, “Upgrade to Windows 11 is on its way to your device. There is nothing that requires your attention at the moment.” This message includes a Learn More link that directs users to additional information regarding safeguards for their PC. For further details, the KB5006965 support document is also available.
In a related development, Microsoft has recently added another upgrade block for Windows 11 24H2, this time concerning systems with Auto HDR, due to compatibility issues that have been causing game freezes.
