I'll pay someone if they'd be willing to Facetime (or similar) and make sense of this whitenoise system (more specifically, how to add music to it).

Howdy -- probably a weird post, but we just took over a building that has this white noise system in it (it works and is active).

I'd like someone to help me make sense of it a bit more (which of the several ethernet ports to plug in to our switch to gain local access -- and what hardware we need to add to get it to play music instead of white noise).
