OS: Windows 10
I cannot select the audio from “Microphone (HD PRO Webcam C920)” as that section is greyed out.
The video is working fine.
This webcam is working fine with the Logitech webcam software; records audio and video no problem.
I use it to record meetings, it is quite sensitive.
I had the same problem with Webcam7 and Webcam XP Pro.
I installed the 64-bit version but could not select an audio source as it was greyed out. Yes, the license was installed.
Then I uninstalled it and installed the 32-bit version but the 32-bit version would not install because of an error.
Even re-downloaded another copy.
