I want to play an audio file over VoIP in order that people can listen to it with a phone call. One way to do this would be to set up the audio file as an audio device where the audio starts playing at a specified time.
There are better ways of playing my file over VoIP, but I'm still curious as to how you would set up the audio device that I discuss. What would I do?
You can see this as the reverse of this question.
