My game sounds are played with noticable delay!

Question

hi.
i'm writing a graphical game by java2D API .
i have many threads to run,so when i use an AudioClip
object to play my desirable sounds (.wav files),it would play
with a noticable delay.
i decided to use windows APIs through the JNI.
but i must first write a c++ code (.h file)then convert it to a
.dll .
i don't know how i can call "sndPlaySound" function of "winmm.dll"
library in C++ code.
can you help me please?
or another recommendation!
thanks a lot.
bye.

Generally it is not hard to do such things. sndPlaySound takes apparently a string and an int to specify the sound and how to play it. You would simply define a native method in your class, use javap to create the native header file and then make an implementation for that native method. The method would take a string and an int and convert them to the format expected by the sndPlaySound function, then just call it and you are done.
I'd suggest passing an array of bytes rather than a Java string. Since a C string is really an array of bytes it is easier to work with it this way. You can do things like converting a Java string to bytes and adding the required NULL terminator from Java code where it is easier to do.
Unless you don't know any C++ coding at all, in which case this could be hard to accomplish.
