Create "Fake" audio device in C#?

Question

I was wondering if it would be possible to create a 'fake' audio device. I've got a program which streams to Twitch and it captures all of the audio on the selected audio device. I want to create an audio device via my own program for this streaming software to listen to. That way it will only be able to stream the sound which I send to the virtual device.

How should I approach this? I'm assuming it's possible because there are fake webcam programs etc which can produce a similar effect but with video.

Unfortunately that is not possible. To create a "Fake audio device" (as you call it), you have to write an audio driver. Download the WinDDK to get a few examples on how to do that. Anyway, you won't find any example coded in C# because it is not possible to write drivers with C#.
