The latest update for Windows 11, version 24H2, has hit a snag with a critical audio-related bug. This issue has left certain PCs entirely mute, disabling sound output across all devices, including built-in speakers, Bluetooth headphones, and headsets.
The root cause? A compatibility issue with Dirac Audio software, which Microsoft and Dirac are now working to resolve. Here’s a breakdown of the situation and what users need to know.
A Bug That Breaks Sound on Windows 11
The 24H2 update, one of the most anticipated feature rollouts for Windows 11, has turned into a nightmare for some users. Reports are pouring in about a complete audio shutdown after installing the update.
Users experiencing the issue can’t hear anything on their PCs, which effectively disables critical features like online meetings, streaming, and gaming.
The culprit is Dirac Audio software, which aims to improve sound quality through its advanced algorithms. Specifically, the issue stems from the software’s cridspapo.dll file, which conflicts with the update.
Microsoft has confirmed this glitch in its official documentation, where it is categorized as a “known issue.” Unfortunately, the exact manufacturer of the affected devices remains unidentified, but Microsoft has stated that only a limited set of devices are impacted.
Microsoft Takes Action With a Temporary Block
To mitigate the fallout, Microsoft has implemented a temporary safeguard hold on the 24H2 update for PCs running the problematic Dirac Audio software. This safeguard ensures that affected devices cannot receive the update until a fix is in place.
This is part of Microsoft’s standard protocol when encountering compatibility issues, preventing users from experiencing unnecessary disruptions.
If the safeguard impacts your system hold, you might receive a message indicating that the update is currently unavailable for your device. While this might seem frustrating, it’s a necessary step to avoid rendering more systems silent.
No Immediate Fix for Affected Devices
For users who have already installed the 24H2 update and are now facing audio issues, there is, unfortunately, no immediate solution available.
Microsoft is collaborating directly with Dirac to address the problem and release an updated driver to fix the bug. Once the driver is ready, it will be rolled out via Windows Update, lifting the safeguard hold and allowing the update to proceed safely for affected devices.
Until then, users are stuck with muted PCs unless they choose to downgrade to an earlier version of Windows 11 or use a workaround like connecting external sound systems that bypass the software conflict.
Other Audio-Related Issues Plague the 24H2 Update
Interestingly, this isn’t the only audio-related glitch tied to the 24H2 update. Another reported issue involves sudden and unpredictable spikes in volume.
Affected users have described scenarios where their systems unexpectedly play sound at maximum volume, potentially causing discomfort or even damage to connected audio devices.
This particular problem has been traced to the Creative Sound BlasterX G6 DAC, a popular external audio interface. Microsoft is investigating the issue and has promised a fix, but as of now, there’s no timeline for its resolution.
What About Gaming? Auto HDR Bug Adds to the Chaos
Beyond audio problems, the 24H2 update has also introduced a visual bug affecting Auto HDR, a feature designed to enhance the graphical fidelity of games.
Users have reported inaccurate color displays, with washed-out tones and less vibrant visuals, detracting from the intended high-dynamic-range experience.
Like the audio bugs, this issue has been added to Microsoft’s list of known problems, with a promise of future updates to address the concern.
How to Stay Safe: Tips for Users
If you haven’t yet upgraded to Windows 11 24H2, it’s wise to wait until these issues are resolved, especially if your system includes Dirac Audio or Creative Sound Blaster devices. Here are some practical tips to navigate the current situation:
- Check for Compatibility Issues: Before updating, visit Microsoft’s release health dashboard to see if your device is listed among those impacted by known issues.
- Avoid Manual Updates: Some users may be tempted to manually install the 24H2 update, bypassing the safeguard hold. This is not recommended for those with affected hardware, as it could lead to a loss of audio functionality.
- Stay Updated: Keep an eye on official announcements from Microsoft and Dirac regarding the release of the updated driver. This fix will eventually allow safe installation of the 24H2 update.
- Create Backups: Before any major system update, create a full system backup to ensure you can revert to a functional state if problems arise.
The Broader Implications for Windows 11
The 24H2 update is part of Microsoft’s broader strategy to refine Windows 11, which has struggled to win over some Windows 10 loyalists.
However, the persistence of bugs in major updates may discourage users from making the switch, especially as Windows 10 approaches its official end-of-life in October 2025.
This isn’t the first time Microsoft has faced challenges with updates. Windows 10, despite its widespread adoption, was also plagued by issues over the years.
However, as the transition to Windows 11 becomes inevitable, Microsoft must prioritize smoother rollouts to maintain user trust and confidence.
What to Expect
Despite these challenges, there’s a silver lining. Microsoft has demonstrated a proactive approach by addressing bugs quickly and collaborating with third-party vendors like Dirac.
Once the updated driver is available, users will likely see the issues resolved, allowing them to enjoy the full benefits of the 24H2 update, including its new features and improvements.
Additionally, the company’s focus on improving user experience through features like Auto HDR, enhanced sound capabilities, and a more intuitive interface shows that Windows 11 is evolving into a robust platform.
However, achieving this vision depends on how well Microsoft navigates and resolves these growing pains.
