Windows 11 24H2 Bug Causes Unexpected Volume Spikes on Gaming PCs
After updating to Windows 11 24H2, some users are reporting an annoying bug where their system’s volume unexpectedly spikes to 100 percent. This issue is primarily affecting gaming-focused PCs and appears to occur without any error messages or other warnings. The sudden increase in volume can be jarring, especially for those using external sound systems for a more immersive experience.
Microsoft has confirmed the bug and outlined the specific conditions under which it occurs. The problem seems to happen when the following factors align:
- Your PC has been updated to Windows 11 24H2.
- You’re using the Creative Sound BlasterX G6 external USB digital audio converter (DAC) sound system.
- You manually put your PC into sleep mode and then wake it up.
- You attach and detach the external DAC sound system immediately.
- You adjust the volume of the external DAC and then quickly disconnect it.
The root cause of the issue has been traced to a timing problem within the AudioEndpointBuilder service, though Microsoft has yet to release more specific details. They are actively working on a solution and plan to update users with further information through the support page once a fix is available.
For now, affected users may need to be cautious when using external DACs, especially if they frequently put their PC into sleep mode or detach devices. Keep an eye out for an upcoming fix, and monitor Microsoft’s support page for updates on this issue.
