Create New project and select Audio analyzer example.
Go to event sheet and comment out first Action from On start of layout event (Play EpicArpg looping at...)
Add following action to On start of layout event: Audio | Preload Lazer Fire 1.
Here is screenshot how On start of layout event should look now:
Run project and you should find out that audio analyzer works every second time when you press mouse button. If you remove that Audio | Preload Lazer Fire 1 action, audio analyzer works every time.
Is this bug or did I misunderstand how Preload action works?
