It says no audio device is installed when I plug in my c920 logitech camera

as an Update for others. I decided to upgrade the Webcam to another (Kiyo Pro) and did not have the issue.

It is really sad that the audio driver dies just because one webcam.

Take a look at this post:

Webcam C920's microphone, along with many other webcams, is conflicting with Realtek's AudioProcessingObject. Microsoft needs to deploy the fix. In the meantime, you can work around the problem by disabling the webcam's audio.

I just bought this Samsung laptop this spring, and have been thinking it was an issue with that ALLLLLLLL summer. So glad to see I'm not alone.

My camera is a Logitech C925e - I figured since is was from work, it would always work.
But here's the thing - the camera kills the audio drivers for my Samsung, but the camera simply WORKS with the HP Elitebook I have. Hmmmm🤔

Henrik, Thanks for creating that ticket (11818597). Just wondering what's the best way to leverage the ticket number to resolve the C920/Win11 audio issue.

I'm seeing the same symptoms as previously reported on this thread. My Win11 laptop audio works until the C920 camera is plugged in and then the speaker icon in lower right of screen get a little black X and a mouseover note that says: "No audio device is installed". There's an option to test and debug the audio issue. After unplugging the camera and allowing the debug to restart audio services, the audio is re-enabled.

Glad to see I'm not the only person having this problem. So many people are seeing this audio issue its surprising Microsoft and Logitech have not made a definitive solution available to their customers.

I have another brand of webcam, same issue!
