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


that title may seem ridiculous have problem. have service capture line-in and, save file on system sound file (that service didn't develop me, , must use that).

so want write program select sound file (*.wav, *.mp3 or etc), , sound file, play on line-in (microphone) record user speech.

q: how in c#? advise?
thanks
