[racket-dev] FFI problem, possibly related to chaperones

I'm having trouble with my sound library in, and I'm getting error messages like this:

play-thread exception: s16vector->cpointer: expected argument of type <s16vector>; given #<s16vector>

This suggests to me that s16vector->cpointer is failing to recognize an s16vector. I'm still debugging, but my first guess is that this is related to chaperones. My first guess was that this could be related to a contract, but I can't immediately figure out how to apply a vector-contract to an s16vector. 

Still debugging,
