And then I have a standard male to male TRS audio adapter cable which I connect to the iphone audio port.

I have the 1more triple driver earbuds which connect to the lightning port on the iPhone.
I want to have the audio playing in real-time from the pc to the iPhone and listen to the audio playback through the lightning port.
I was searching for apps which can route audio this way, the only thing I found which slightly works is the "Live microphone" app. But it doesn't work very well.
Do you know of any other apps which may provide this possibility?
Another thought is to stream the audio from my pc on a server, and then connect to the server on the iPhone. But it sounds tedious and I don't know if I can do that without some server hardware.
