Hi VipinRana1,
My name is Darren; an Independent Consultant, I'm here to help you with your problem.
Since this issue started occurring after a recent windows update, you can try roll back driver:
Go to Start > Type "Device Manager" and hit enter > right click on the microphone drivers > select properties > select driver tab > click roll back driver
If roll back driver isn’t available or did not work, you can try uninstall both microphone drivers and scan for hardware changes:
Go to Start > Type "Device Manager" and hit enter > right click on the driver > select properties > select driver tab > click on uninstall device > select "Delete the driver software for this device" and click OK > In Device Manager, on the Action menu, select Scan for hardware changes > Wait for it to scan and reinstall the driver then restart your pc and check if the issue still persists.
I hope this helps. If this is not exactly what you need, please explain more so that I can help you better.
Thanks
