Bug in Windows 11 24H2 Causing Sound Levels to Jump to 100% on Gaming PCs
A bug introduced with Windows 11 24H2 has led to a significant issue for some users: the volume on their gaming PCs suddenly increases to 100 percent, with no clear warning or error messages. This problem seems to be most common among users who employ external audio systems, and it’s proving especially disruptive when using a specific DAC system.
Microsoft has confirmed the bug, explaining that it occurs under the following conditions:
- The system has been updated to Windows 11 24H2.
- The user is utilizing a Creative Sound BlasterX G6 external USB DAC.
- The PC is manually placed into sleep mode and then woken up.
- The external DAC is attached and immediately detached from the PC.
- The volume of the DAC is adjusted and then the device is detached shortly after.
The cause of the issue has been traced to a timing glitch in the AudioEndpointBuilder service, though Microsoft has not released further details on the technical specifics. The company has assured users that a fix is in the works, and they will update their support page with more information as soon as it becomes available.
For now, users experiencing this bug should be mindful of their external DAC connections and volume adjustments, as these actions seem to trigger the problem. Stay tuned for Microsoft’s official update to resolve the issue.
