Simple question, or is it...

What exactly is an audio signal made of, and what exactly is the medium it travels through in a cable??

It is strictly not between wires since electric fields bends, but also outside of the cable in-between planes like picture below shows: https://www.google.com/url?sa=i&url=http%3A%2F%2Fwww.vias.org%2Falbert_ecomm%2Faec06_transmissio...

What is it that travels down the near lightspeed? Current? the EM wave? Surely not the Poynting vectors, yes? Something must be traveling down the inside of the conductor, otherwise the type of metal, gauge and purity of the conductor wouldn’t matter, yes?
