Microsoft has resolved a significant audio bug in Windows 11 version 24H2 that prevented Bluetooth headsets and speakers from functioning correctly on certain devices.
The issue, which first appeared in December 2024, has now been fixed through a new driver update, and the company has lifted the temporary block that prevented affected users from installing the latest version of the operating system.
The problem originated from a software incompatibility on a specific set of devices from a single manufacturer that utilize Dirac Audio technology.
After installing the Windows 11 24H2 update, users on these machines reported a complete loss of audio output. The issue affected integrated speakers, connected Bluetooth speakers, and wireless headsets, with applications failing to recognize the audio hardware.
Microsoft’s investigation identified the root cause as a conflict with the cridspapo.dll file, a software component associated with the Dirac Audio processing suite, which is designed to enhance sound clarity and precision.
To prevent more users from encountering the audio failure, Microsoft initiated a “compatibility safeguard hold” on December 18, 2024. This measure automatically blocked devices containing the problematic cridspapo.dll file from receiving the Windows 11 24H2 update through the standard Windows Update channel.
Users with affected hardware would see a message in their settings indicating that the upgrade was on its way but temporarily paused, directing them to more information about the specific safeguard hold (ID: 54283088). This proactive step ensured the issue remained contained while a permanent solution was developed.
As of September 12, 2025, the audio issue is officially resolved. Microsoft has released a new version of the audio driver via Windows Update that corrects the incompatibility. Consequently, the company removed the safeguard hold on September 11, 2025.
Users with previously affected devices should now be able to install Windows 11, version 24H2, without issue, provided no other compatibility holds are in place.
Microsoft advises that it may take up to 48 hours for the update to become available to all eligible devices, and a simple system restart might help expedite the process. Users are encouraged to install the latest security updates to receive this and other important fixes.
