Microphone problems after the Windows 10 April 2018 Update

For some users Windows 10 is now blocking Audacity from using the microphone, on the basis of privacy settings.

After upgrading to version 1803, some users have been reporting that the microphone is getting detected, but it doesn't pick up any sound.

In order to get around this issue, Microsoft recommends that you need to enable the microphone in your Privacy settings using these steps:
1) Open Settings
2) Click on Privacy
3) Click on Microphone
4)Turn on the Allow apps to access your microphone toggle switch.

Update: you may also need to do this if Audacity was working on Windows previously but you now get the "Error opening sound device ..." message.
