which audio codecs ? you mean the ACM ones ?
there are loaded as any drivers, looking for their names in
system.ini drivers32 entries. to use the native acm codecs, 
you need something like:


(btw, video codecs are loaded the same way, so it's strange it
doesn't work. any trouble somewhere with the .acm extension  in
the loader somewhere ??)

well it depends how the program was first compiled. there are
options on windows to compile a program as:
- without fpu (force always emulation)
- only with fpu (no emulation)
- mixed strategy (if fpu present, then use it, otherwise fall
  back to emulation)
so, it sounds like the fpu traps are not correctly handled between
wine and solaris (hard to tell more here)

don't worry about that. all this code should be removed real soon
(if Alexandre commits my patches ;-)
