Summary
Microsoft says the November 2026 cumulative updates fix a USB audio problem that has affected Windows users who installed security updates released since September 2026. The issue hits USB Audio Class 1.0 devices.
Symptoms
- No audio output from affected USB devices
- Volume controls and sound settings that stop responding
- "This device cannot start (Code 10)" errors in Device Manager
- On some systems, USB audio speakers fail only in multichannel modes such as 3D audio or 8-channel audio
Affected Systems
Windows 10 and Windows 11 (client and server), plus Windows Server 2012 and later.
Fix
- Out-of-band updates released on September 14, 2026 addressed the 8-channel and 3D audio symptoms.
- The fix for the remaining issues is in the Windows security update released November 10, 2026, KB5132061, and later updates.
What To Do
Install the latest cumulative update. Microsoft has not published an official workaround for systems that cannot yet take the November updates. Some users reported restoring audio by switching their devices to 2-channel mode.
