How to make music start at begin, then stop at trigger?

Shouldn’t be a difference in this from 4.10.2 - 4.10.4…

I don’t understand what you mean by you “see the list, but don’t see any files in it”? A ‘list’ would indicate items are contained within, like a ‘Shopping List’ or a music ‘Play List’.

Take a look at this image. It shows the 2 test audio files I have… Well 1 audio file and a sound cue made from that audio file.
