Microsoft has acknowledged that its recent September security update for Windows 11, identified as KB5124008, is leading to a series of audio-related complications, particularly affecting USB audio devices. Users have reported issues such as unresponsive sound controls and, in some cases, a complete lack of audio output.
Details of the Audio Issues
The update appears to disrupt audio functionality on USB devices, with symptoms ranging from silent outputs to non-responsive volume controls and inaccessible audio settings. While these problems have surfaced following the installation of the September update, they do not seem to impact every device uniformly.
For those experiencing audio difficulties, a useful diagnostic step is to check the Device Manager logs for the error message “This device cannot start (Code 10).” Reports have also emerged regarding affected microphones, although Microsoft has yet to officially address this aspect.
It is important to note that the issue is confined to USB Audio Class 1.0 devices, which adhere to a universal standard for plug-and-play digital audio over USB. Fortunately, built-in motherboard analogue audio codecs and wireless headsets remain unaffected by this particular bug.
Attempts to resolve the issue by uninstalling and reinstalling the device driver will not yield results, as the root cause lies within the Windows Update itself. Microsoft has confirmed that it is actively working on a solution. In the interim, users may find some relief by switching from 8-channel or 3D audio modes to stereo settings.
Broader Impact of the Update
Beyond audio issues, the KB5124008 update is reportedly causing gameplay disruptions, including crashes, freezes, errors, and unexpected device restarts, particularly for systems connected to RGB peripherals. These complications add to a growing list of previously documented bugs, which include black screens, malfunctioning File History backups, and challenges with Claude Cowork and Remote Desktop functionalities.
If you are encountering any of these issues, it is advisable to report them to Microsoft to ensure they receive the necessary attention. Additionally, if you have not yet applied the KB5124008 update, you might consider pausing updates on your system until a resolution is provided.
