Personally I think this isn't a fully correct way of use of the LoadSound command. while in other Languages such assignements might work properly, I woulndt event try it in Blitz.
Instead try this:
Instead try this:
vh_fadeintro_sfx = LoadSound ("audio/fade-intro.wav") If vh_fadeintro_sfx <> false Then SoundVolume (vh_fadeintro_sfx,maxvolume) PlaySound (vh_fadeintro_sfx,infinite) Else RuntimeError "error" End If
