Well, we’ve got some holiday troubleshooting on our hands, folks! Microsoft’s highly anticipated Windows 11 24H2 update—an incremental feature release intended to add polish to the Windows experience—has run into a pair of significant issues that are leaving users in the lurch. Not only is it breaking audio output on certain machines, but it’s also causing havoc with Auto HDR, a feature beloved by gamers and video enthusiasts alike. Let’s dig into the details, figure out what's at play under the hood, and determine what this means for you as a Windows user.
For some systems—specifically those manufactured by a mystery vendor using Dirac Audio technology—the Windows 11 24H2 update is turning the world’s most basic computer feature into an exercise in silence. Microsoft confirms that the culprit is the "cridspapo.dll" module, a piece of software responsible for delivering clearer and more precise sound using the Dirac Audio system. Essentially, this DLL file seems to have gone rogue in the new update.
Here’s a breakdown of what’s happening:
The block acts as a failsafe in Windows Update and ensures systems don’t accidentally download a problematic version. For advanced users, however, forced installation is still an option. (But seriously, just don’t. Wait for the patch.)
But this also raises questions: Is Microsoft rushing these feature updates? Are they prioritizing new features over ensuring compatibility and stability? For impacted users, these are fair concerns.
To their credit, Microsoft’s swift block on impacted systems prevents the crisis from spreading further. Still, hearing silence or dealing with glitchy games doesn’t exactly inspire confidence in early adopters.
In the meantime, we’ll be keeping a close eye on Microsoft’s progress. Let’s hope they roll out a fix soon because Auto HDR and premium audio are features worth fighting to preserve—just not at the cost of your sanity.
Have your own Windows 11 woes to share? Sound off (pun intended) in the forums. Let’s troubleshoot this monster together!
Cheers to better updates ahead.

The Issue with Audio: A Silent Killer
For some systems—specifically those manufactured by a mystery vendor using Dirac Audio technology—the Windows 11 24H2 update is turning the world’s most basic computer feature into an exercise in silence. Microsoft confirms that the culprit is the "cridspapo.dll" module, a piece of software responsible for delivering clearer and more precise sound using the Dirac Audio system. Essentially, this DLL file seems to have gone rogue in the new update.Here’s a breakdown of what’s happening:
- Devices Affected: Systems equipped with Dirac Audio software.
- Symptoms: Complete loss of audio output across all devices—whether it's the built-in speakers, Bluetooth devices, or wired headsets.
- Workaround: None, nada, zilch. For users affected, audio output won’t work until Microsoft patches the update.
Tech Breakdown: What Is Dirac Audio?
Dirac is a Swedish company specializing in audio optimization software, often found in high-end laptops and premium desktops. Its software works behind the scenes to tune audio parameters for better clarity, spatial depth, and bass response. Cridspapo.dll, specifically, seems to handle signal processing for these tasks. The fact that this update completely breaks its functionality shows just how fragile software dependencies can be. One poorly tested line of code, and suddenly, your Netflix binging marathon becomes a silent film experience.Auto HDR: A Recipe for Disaster
Gamers and video enthusiasts, brace yourselves. One of Windows 11’s headline features, Auto HDR, is also stumbling hard in this update. Auto HDR, for the uninitiated, is designed to convert traditional SDR (Standard Dynamic Range) content into vibrant HDR (High Dynamic Range) visuals. When it works, it’s pure beauty. When it doesn’t? Well, you’ve got color glitches, unresponsive games, and outright crashes.How Does Auto HDR Work?
Auto HDR uses a software-based algorithm to identify SDR content, process its visual metadata, and render it in HDR on compatible displays. This technology essentially transforms older games or video content that weren’t built for HDR into something more visually stunning by widening the contrast and color range. However, this additional processing places strain on both software and hardware, which could be why the 24H2 update is causing such significant malfunctions.The Symptoms
- Color Issues: Incorrect color profiles appearing on the screen.
- Loss of Game Functionality: Games freezing or outright crashing while Auto HDR is active.
- Temporary Workaround: Turning off Auto HDR appears to fix the issue for now. But that also means saying goodbye to all the eye candy and visual enhancements the feature provides.
Microsoft’s Response and Blocked Updates
In response to widespread user reports, Microsoft has opted to block the Windows 11 24H2 update on systems affected by either issue. The update will remain unavailable for these PCs until the company delivers a fix, restoring audio and Auto HDR functionality. While this may cause frustration for those eager to jump on the latest update bandwagon, it’s probably for the best. Nobody wants to deal with gaming in neon green or explain to Grandma why her laptop won't play “Jingle Bells” anymore.The block acts as a failsafe in Windows Update and ensures systems don’t accidentally download a problematic version. For advanced users, however, forced installation is still an option. (But seriously, just don’t. Wait for the patch.)
What Should You Do If Your PC Is Affected?
If you’re already on 24H2 and dealing with these issues, here’s your action plan:- Turn Off Auto HDR:
- Go to Settings > System > Display > HDR.
- Locate the Auto HDR toggle and switch it off.
- Revert the Update (if extreme silence isn’t your thing):
- Navigate to Settings > System > Recovery > Go Back, assuming you’re within the 10-day rollback window.
- Keep an Eye on Updates: Microsoft is working on patches, and they’ll likely roll out as part of cumulative updates over the coming weeks. Watch your Windows Update center for details.
A Broader Perspective: Why This Keeps Happening
The good—and bad—news is that software bugs like these highlight the complexity of today’s ecosystem. Windows 11, in particular, is a patchwork of technologies that need to work across millions of different device configurations. Add in OEM-specific software like Dirac Audio, GPUs configured for Auto HDR, and the fast-paced development cycle of Windows, and you’ve got a blank canvas for chaos.But this also raises questions: Is Microsoft rushing these feature updates? Are they prioritizing new features over ensuring compatibility and stability? For impacted users, these are fair concerns.

Closing Thoughts
To anyone affected by this update: hang tight, stick to stable builds, and remember, it’s always worth waiting a few months before jumping onto the latest feature update. Let someone else play guinea pig for a change.In the meantime, we’ll be keeping a close eye on Microsoft’s progress. Let’s hope they roll out a fix soon because Auto HDR and premium audio are features worth fighting to preserve—just not at the cost of your sanity.
