FYI, I finally ditched the Logitech webcam and went with a standalone USB mic, as I rarely used video on the PC.

Now, since with Windows 1903 update, Skype won't retain my mic settings. It's a simple matter of changing from default audio output to the USB mic in Skype settings, but it's still a hassle. For this reason and others I've ditched Skype, too, and use other software like Zoom.
That's great to hear that it just seems to be a Logitech issue. I've heard reports of this issue from multitudes of different Logitech web cams. Seems they just don't care to update their drives. I did report the issue to Logitech in 2017 and heard others had done the same but been told to 'contact Microsoft'. I just reported again to Microsoft and they told me to 'contactLogitech'. I can't afford a new mic at the moment and think Logitech should make their mics work..
