How to fix
Logitech Pro Webcam audio bug
on Windows

Hello. I have the Logitech Pro Webcam C920 and I use it with my Windows 11 PC. Every time I plug it in, it shows the "no audio device is installed" error message. At first, everything was working fine, but now the webcam audio is not working anymore. Is there anything I can do? 

With its exceptional quality and versatility, the Logitech Pro Webcam C920[ref en-1] provides users with an improved video communication experience. With a full HD 1080p resolution, it provides clean and sharp images for streaming, video chats, and content production. With its sophisticated Carl Zeiss optics, the webcam produces clear, detailed images. Its twin stereo microphones record crisp, high-quality audio to go along with its amazing visual capabilities.

However, there appears to be a persistent audio bug affecting Logitech Pro Webcam users on Windows, as reported by many users encountering issues on their Windows 11 systems since July. The issue appears when the Logitech C920 Pro Webcam is plugged in and displays the message "no audio device is installed". After some research, one user found a solution that resolved the issue for them, indicating a possible incompatibility between a certain Windows patch for Realtek's AudioProcessingObject and the Logitech Webcam. This conflict leads to the unexpected termination of the Windows Audio service.

Users who depend on the Logitech Pro Webcam for audio capability may be greatly impacted by this problem, which can impede conversation and make the device practically useless in terms of audio functioning. The error message that indicates there isn't an installed audio device might be very annoying for consumers who might not be aware of the conflict at the root of the issue. This could lead to people wasting time trying to find a solution or, in more serious situations, possibly resorting to buying new hardware when it's not necessary.

One possible way to help impacted users would be to resolve the conflict between the Logitech Webcam and the Windows patch. Additionally, keeping an eye on official updates from both Microsoft and Logitech for patches or driver[ref en-2] updates addressing this specific conflict may prove beneficial in resolving the issue.

In this guide, you will find 3 steps that should do the job as a workaround in the meantime.
