most packages will tell you what format and codec the file is in.
It may be a case of the codec or the format settings at export from the original sound thats making it quirky.
If it was required for a 3dsound then one requirement is a mono version since DB emulates the 2 speaker volumes to make it sound 3d i guess.
stuff to test within your wav file.
codec
the bitrate
the khz
any additional file format settings
if its either stereo or mono
most wav editors will allow you to resave the file in different formats and options
