Very few sounds playing in packaged game despite all playing in editor

When I package (for windows) my game most sounds are not playing, nor does any of the music. They occasionally wont play in the editor either in the same manner, but if I resave all in contents then it fixes it for a period again until I’ve edited some amount of things (of which I am compiling and saving as normal).

I say most in that all sounds have been setup the same as the others in their class in both wave and cue but play when others do not. Of the three sound classes there is one sound in the SFX class and that plays fine, with barks 1 of the 3 play, and none of the music play.

And incase I made some kind of simple mistake I’ve taken some screenshots below to show how I’ve set things up, again they do play properly when resaved so I presume its struggling to find them in some way but I don’t know how I could proceed further with this kind of problem so any help is very much appreciated.

Additionally, this is a mobile game with ui sounds only so that may be worth mentioning.

I set up the sound base mix on the splash screen game mode (as well as in default just incase, though I know there’s it does seem to work and was a changed I made while trying to solve this so I doubt is related to the cause here)


How I have set up my sound class ‘master’


The wave file are like this


And the sound cues like this


And how I’m using the soundmix
