Windows 10: All Windows 11 Audio Outputs Disappearing when my Logitech C920 webcam is plugged in

I just purchased a new laptop a couple of weeks ago and I've been encountering this problem with the audio. I use a Logitech C920 webcam, and I have it plugged into a USB Switch and it's functioned fine with previous laptops where I've had this setup. With Windows 11, however, I'm running into this issue where when I have the webcam plugged into the USB switch, all audio on the laptop stops working. The microphone cannot be found and the ability to listen to audio is also not there, it keeps saying that the microphone and speakers are not detected. The moment I plug the webcam directly int

C920 Logitech Pro Webcam - Win 11 Audio Bug – A Workaround

Since July, my Windows 11 laptop says “no audio device is installed” when I plug in my C920 Logitech Pro Webcam. After much searching, I found a fix that works for me. The problem is a conflict between a specific Windows patch for Realtek's AudioProcessingObject and Logitech Webcam, which causes the Windows Audio service to terminate unexpectedly.

Here are work-around steps I'm using to re-enable audio.

1. With the Webcam plugged in, disable the Webcam's Audio Component:
   
   - In Device Manager, under "Sound, video and game controllers", find the "HD Pro Webcam C920" entry.
   
   - Right-click on "HD Pro Webcam C920" and select "Disable". Confirm any prompts if required. Here's an image showing the webcam after it has been disabled in Device Manager:
   
   
   
   
   
2. Restart the Windows Audio Service. If audio doesn't restore within 30 seconds after disabling the webcam's audio component, try manually restarting the Windows Audio Service. Here's a quick way:
   
   - Press Win + R to open the Run dialog
   
   - Type services.msc and press Enter.
   
   - In the list of services, scroll down and find "Windows Audio".
   
   - Right-click on "Windows Audio" and choose "Restart".
   

That's it. If you disable the "HD Pro Webcam C920" audio component in Device Manager, that specific device should remain disabled across reboots until you manually re-enable it. So, in that sense, it won't need to disabled again every time you restart.

Good luck.
