Polycom Communicator C100s Windows 10 Driver Access

Short Answer: No. There is no official Polycom Communicator C100s driver for Windows 10. Polycom never released one.

Long Answer: The device should work using Microsoft's native USB Audio 1.0 Driver, which has been baked into Windows since Windows 8. However, "should work" and "does work" are two different realities. Many users report that while the device is recognized as "Polycom C100s" in Device Manager, the microphone or speaker fails to function correctly after a Windows 10 feature update.

Cause: On very rare occasions, Windows 10’s memory integrity (Hypervisor-protected Code Integrity) blocks old unsigned drivers. Fix: Short Answer: No

Run Windows Update again (it may fetch the driver).

Try different USB ports and a different cable; test on another PC to isolate device vs. host problem.

The Polycom Communicator C100s is a portable, high-quality speakerphone designed for unified communications (UC). It connects via USB and provides wideband audio for calls, web conferencing, and multimedia playback. While the C100s is a legacy device, it remains fully functional on Windows 10 with the correct driver configuration. Run Windows Update again (it may fetch the driver)

For IT managers deploying C100s across an office (why?!), you can force the generic driver via PowerShell:

pnputil /add-driver C:\Path\To\usbaudio.inf
pnputil /install-device "USB\VID_045E&PID_07XX" (Replace with actual C100s hardware ID found in Device Manager)

Then, disable the built-in Realtek audio via registry to ensure the C100s takes priority.
