Polycom Communicator C100s Windows 10 Driver -

Polycom Communicator C100S does not have official driver support for Windows 10

Step 4: Microphone Privacy Settings (The Silent Killer)

The #1 reason the C100s appears to "work" (speaker outputs sound) but the microphone is dead on Windows 10 is Microphone Privacy Settings. Polycom Communicator C100s Windows 10 Driver

The device appears as "USB Audio Device" — not "Polycom C100s." No drivers install. No software utility launches. You test it. The microphone picks up a faint, robotic buzz. The speaker works, but only in mono, and at a volume that whispers secrets rather than projects authority. The beautiful noise-canceling array? Dead. The hardware buttons (volume up/down, mute, call answer/hang up)? Useless—ghosts of functions past. Polycom Communicator C100S does not have official driver
