If it is something that you need to use often, then I recommend using "Play Sound" only (forget the condition), in a script called by other action
. Just rename the text "called by other action" to something more specific, like "Refrain". So it's easier to call your sound anytime.
You should place this script in a place where it is easy to access (in an empty scene with only some global scripts, for example).
Then when you work in your other scenes and need to call your refrain, you just need to use an action "call/quit action
" and set it on "Call", and point to the special Refrain script.
I'm not sure it will solve your issue, I didn't exactly understand what you want to do, but hopefully you'll figure out what to do
