Playmaker Interactivity tutorial

So for this assignment, i decided to make a scene from scratch. The scene i had in mind was that of a wild wild west with a twist. I placed two characters i downloaded from mixamo and made them dance to the trigger- which in this case was a skull on the ground. As soon i would get close to the skull, the music would start playing and the characters would dance.

It took me some time to get the logic right but once i did playmaker didnt pose much problem. Although i need to practice it a bit more to get fully used to it.

There were a couple of problems i faced though, for instance the volume on the music was very low. I looked up online and it suggested me to change the audio to 2D from 3D in the inspector, which i did, but still it didn't help. Another problem i faced was that whenever i would exit the trigger, the music would keep on playing.I also added  an action "Audio Stop" in playmaker hoping that would work. Unfortunately that didnt work as well.
