[SOLVED] Logitech HD Pro webcam c920 mic not working with apps (but tests OK in Settings)

[itm]

The microphone on my Logitech HD Pro webcam c920 has stopped working with Skype, Zoom, Camera and other apps. The camera works fine. If I troubleshoot the device in the "Test your microphone" section in Windows settings it seems to work fine - i.e. I see the input level respond when I speak into it. If I choose the "Troubleshoot" option it says it couldn't identify the problem.
I've tried:
- uninstalling the Logitech webcam software
-unplugging the webcam from USB
-removing the webcam driver from Device Manager
-rebooting (the driver was reinstalled after reboot).
Any idea why the mic doesn't work with Skype, Zoom, Camera apps??

OK I managed to fix it. I went into Control Panel...Hardware and Sound....Manage Audio Devices....Recording. In the Advanced tab I set Default Format to "2 Channel 32 bit 32000Hz (FM Radio Quality)". It was previously set to 16,000Hz (Tape recorder quality). Now the mic works in Zoom.
