Monitor microphone changes

Question

Is there any way to monitor microphone changes (plug in and plug out events)? Shouldn't matter if the mic is bluetooth / usb / or plugged directly to sound card. Application is built with C# but if there isn't any good way to get the events using C# then C++/CLI might be also option.

If the microphone appears as a separate device (eg. shows in device manager) you can almost certainly use WMI events. — Richard, Nov 28 '14 at 13:19

I found also IMMNotificationClient from WASAPI which should work. Seems NAudio is not exposing this, but after customization I'm able to use it and get plugin / plugout events. Although it doesn't seem really stable - duplicated events / missing events and etc. Is there any proper implementation example in managed level?
