Articulate Storyline 360- Music across specific slides - how to stop it?

Hi again. I replaced my current initialization script/trigger with your "initialize and play audio"  script.

I also deleted my 2nd script

TRIGGER 2

var audio = document.getElementById('bgSong');
audio.src="Jeopardy 3 Minute music Mixdown JHenry.mp3";
audio.load();
audio.play();

When publishing, there is no audio whatsoever.

Then, I added your "play audio" script as an additional trigger (both triggers on Slide 2).

Published, and no audio is heard.

I think I need a more granular step-by step in order to get this right and to know what to put where and what not to include.

Also, I was a little confused about why you included both an "initialize and play audio" and also a "play audio" script.

I want to do 3 things

1. initialize and play a 3-minute audio (from slide 2), continuously throughout progress through the slides.

2. Stop that audio when user reaches a target slide. Meaning the user has reached the slide before 3 minutes.

3. Don't loop the audio that was started on Step 1. It naturally ends after 3 minutes because it is a 3-minute audio.

So I don't need to pause the audio or restart it at any time, once it has started.

Thanks for your responses and time, Jürgen. I know it's not helpful that I don't know javascript, lol.
