All semblances make a sound because when your aura becomes tangible to the world it disturbs the air. As someone who deals with music I know when you have a score if you have a sound that represents a character you use it in music to represent them. And a semblance is a representation of the characters. Okay, but you completely missed the point that everyone else's Semblance noises are not part of the background music.

On top of that, there's a difference between "This is a character's leitmotif" and "This signifies that the character has used their Semblance".

So, no, it's not Cinder's Semblance noise. It's just a leitmotif noise, aka a "Hey, Cinder is in this scene!" noise.
