How to make a radio station on YouTube Live?

Question

YouTube

Given:
1. Xiaomi WIFI Router with hard on board and a huge iTunes audio library.
2. A Mac computer and iTunes, which take this audio library over the air from the router.
Well, actually the question itself - how to make friends with this whole thing?
I tried all the software recommended for live broadcasts from Google. Could only run video in Wirecast and OBS. Sound from tuna does not want to cling to any through these programs.
Any ideas where to dig? Maybe there is some more adequate and professional software for video broadcasts? I would like to organize a radio station on YouTube, something like that - https://youtu.be/NRw339i17yw

Answer 1

OBS studio
Why is there no sound when streaming via OBS on MAC?
