Windows 11 out-of-band update fixes audio glitch and other bugs – grab it now
The latest out-of-band update resolves a few problems in Windows 11, including one that cut off the sound for certain USB audio devices.
Microsoft has released an out-of-band patch to fix an audio bug in Windows 11. This update is available for Windows 11 26H2, 25H2, and 24H2 versions. The issue affected USB Audio Class 1.0 devices, which use an older, legacy audio driver from Windows 98. Users experiencing the bug may have encountered problems playing audio on USB-connected headsets, speakers, and other devices.
The only workaround before the patch was to switch to standard stereo mode. The problem originated with Microsoft's September 8 security update, which sometimes introduces new issues. This particular bug was severe enough to warrant an out-of-band patch, as it only impacted older devices. Additionally, the update fixed security vulnerabilities CVE-2026-62721, CVE-2026-85921, and addressed other issues, including a glitch causing Microsoft Remote Desktop Services to become unstable.
To install the update, users should navigate to Settings, select Windows Update, and find the update labeled "2026-09 Security Update (KB5129195)" for Windows 11 26H2, or "2026-09 Security Update (KB5129194)" for Windows 11 25H2 and 24H2.
