Do you already have a solution for this problem with linking the hss.lib in VS2003 ?!
I have the same problems, and do not really want to go back to VS6

Note: I get the LNK2019 linker errors for the methods that return an (unsigned) int (a s32 or u32) or that have a parameter that is of type s32 or u32.
For instance the hssSpeaker.suspend() (returns void and void parameters) does link OK !
Hopefully this helps...
