Windows 11/Server 2025: USB Audio Class 1.0 devices fail (Code 10) or give no sound
Summary
USB Audio Class 1.0 devices reportedly fail with Code 10 or produce no sound on Windows 11 and Windows Server 2025. This is reported by users, not yet confirmed by the vendor. No permanent fix has been found; a third-party page claims the Windows Server 2022 update KB5126655 fixes it, which is unverified.
Symptoms
- Device Manager shows Code 10 for USB Audio Class 1.0 devices.
- Multichannel audio modes fail.
- Devices give no sound.
Affected
- Windows Server 2025
- Windows 11 26H2, 25H2 and 24H2
- Windows Server 2019
- Devices using USB Audio Class 1.0 (USB audio headsets, interfaces)
Workaround
No workaround known.
Fix
Not fixed yet. A third-party page names KB5126655 (Windows Server 2022) as a fix; this is not confirmed by the vendor.
Recommendation
Before rolling out the update to systems that depend on USB audio (e.g. headsets, conference devices, terminal servers), test it with those devices. If affected, pause the rollout on those systems and watch the Microsoft release health pages for an official statement.
