There are many SoundResource's that do not play in the "Play Sound" box of the editor. Is there some trick to getting these to work? If I add the SoundRecource to a MusicVolumeTrigger and walk into it, it seems to work fine.
There's a few SoundRecources that DO play in the editor, but most do not.
One that plays: Idan_Presentation_Music
One that doesn't play: Explo_Theme_11_Dark
