class casing
{
// Name to display in mission editor
name = "casing";
// Sound path, volume, pitch
sound[] = {\sound\casing.ogg, db + 0, 1.0};
// Sound title text (set to no text)
titles[] = {};
};
Here's a snippet from one of my description.ext's. The only difference I can see between yours and mine is that you don't specify a directory (though I can't imagine this being the cause). In addition to what I said about the sounds being 16bit, make sure that the sounds are mono, and not stereo.
I've never encountered this issue before. A fault within the description.ext will cause the game to CTD, but an error message is always given afterwards.
If you haven't already, try using Chris's OFP Editor tool, or ArmaEdit.exe. Both should be available from the editors' depot. These will create a description.ext for you.
Hope this helps
