sound cards get screwy every once and a while, probly just a coincidence.
you don't have FSO on d but I do, more over that's were I keep my copy of the source code, that error mesage is pointing me to the exact point were a problem is found (not caused), and seeing as this is the second time I have seen an error of this type in this function that means it's probly not random like I was hopeing it was (ie someone has to fix it). is this error reproducable and if so, what are the conditions (what mission, what happens right before or as this error gets set off)
