c# - How to Play a sound file on line-in (Microphone)?

Question

That title may be seem Ridiculous but I Have problem. I have Service capture line-in and, save file on system as sound file (that service didn't develop by me, and I must use that).

So I want to write program to select sound file (*.wav, *.mp3 or etc), and then that sound file, will be play on Line-in (Microphone) to record as user speech.

Q: So How Do this In C#? Any Advise?
Thanks

Answer 1

You need to use a virtual audio device driver (like this for example), which will allow you to play audio to that output device and it to appear as an input device to another application. Alternatively, just use a physical cable to connect an output to an input (taking care not to cause a feedback loop).
