I am unable to get createjs.Sound to play sounds

[anagrath]

Sample code snippet:

sounds = [
      id: 'highlight', src: 'highlight.mp3'
    , 
      id: 'click_button', src: "click_button.mp3"
    ,
      id: 'flip', src: "flipOutX.mp3"
    , 
      id: 'pyro', src: 'pyro.mp3'
    , 
      id: 'confetti', src: 'confetti.mp3'
    ]
    createjs.Sound.registerSounds(sounds, "https://s3.amazonaws.com/mybucket/sounds/")
    setTimeout ->
      console.log "***************************** TRYING TO PLAY HIGHLIGHT!!!!! *************"
      sound = createjs.Sound.play 'highlight'    
      console.dir sound
    , 5000

This code works with another application that I wrote in angular. The current is using webpack with react. The canvas code using createjs works perfectly, and now I was going back to reimplement the sounds. I can see the sounds loading from the server with no error. I have a 5 second delay because I have some webspeech within this application and I wanted this to play after the webspeech in case that was interfering with the audio (or drowning it out). I also have a play attached to a button click... Neither play. output of the logs:

***************************** TRYING TO PLAY HIGHLIGHT!!!!! ************* 13:19:15.951 game_layout.js:278 WebAudioSoundInstance

I opened the object and confirmed the URL and everything looks normal. except for the "playState" field is "playFailed"
