Microsoft fixes audio failures caused by September security updates

The November 10, 2026 update addresses issues with USB audio devices in Windows 10, Windows 11, and Windows Server 2012 and later versions of the server system.

The failure affected devices using the USB Audio Class 1.0 standard. On some systems, after installing the updates, these devices either failed to start or did not play sound. Users also reported non-functional volume controls and sound settings, and the Device Manager displayed the error "This device cannot start (Code 10)."

For some systems, the problem occurred only when using multi-channel audio—such as 3D audio or eight-channel mode. On September 14, out-of-band updates were released to address these symptoms. The remaining cases were fixed in the KB5132061 security update and subsequent packages.

The company recommends installing the latest security update. There is currently no official temporary solution for devices that cannot immediately receive the November package. However, some users restored sound by switching the audio mode to two channels.

Along with the November updates, issues with signing into Outlook and mail delivery on Exchange Server, caused by the October 2026 Windows Server security updates, were also resolved.
