I was very confused as to why I was able to hear hear the mic working through control panel when I selected 'listen to this device' but Audacity and Skype etc were unable to use the mic. I chanced upon your reply about the apps, which immediately made sense. After much messing about with trying to remove the drivers and re-install etc. Apparently, with the Windows update to v1803 these settings were modified.I got this update pretty late and when my Logitech C310 webcam stopped working I was sure the update had messed with the drivers somehow.

I am able to Skype again and the problem is solved. Now Windows allows to approach the Webcam. In settings, go to Privacy, Camera and check: Allow which apps can access your camera. For a worry-free streaming and sharing experience, this HD webcam comes with a 2-year limited hardware warranty.Thanks for reactions, but it turned out not to be a driver issue, but a settings issue.
