Audio Audio Manager Prefab not working.

I have an Audio Manager system that rotates sounds for actions. I works fine for level 1 where it was made. I then turned it into a prefab and it doesn't work on further levels. Is there something I'm missing?

I confirmed that the Audio Manager is getting the signals by having it print the name of the signal.

The Audio Manager is from this video.

Thank you very much.

 

Same problem, don't know how to fix it, audio works otherwise but not through the audio manager
