[英]Monitor microphone changes

Is there any way to monitor microphone changes (plug in and plug out events)? 有什么方法可以监视麦克风的变化（插入和插入事件）？ Shouldn't matter if the mic is bluetooth / usb / or plugged directly to sound card. 麦克风是蓝牙/ usb /还是直接插入声卡都没关系。 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. 应用程序是使用C＃构建的，但是如果没有使用C＃来获取事件的好方法，那么C ++ / CLI也可以选择。

I found also IMMNotificationClient from WASAPI which should work. 我还从WASAPI找到了IMMNotificationClient，它应该可以工作。 Seems NAudio is not exposing this, but after customization I'm able to use it and get plugin / plugout events. 看来NAudio没有公开这个，但是自定义后我可以使用它并获取插件/插件事件。 Although it doesn't seem really stable - duplicated events / missing events and etc. Is there any proper implementation example in managed level? 尽管它似乎不太稳定-事件重复/事件丢失等。在托管级别是否有适当的实现示例？
