Dave Korn has already replied, why don't you address his comments rather then reposting the same message. If you're hoping to get help with your problem then repeating yourself over and over is not the way to go about it.

signal issue
I try to kill a process under cygwin. The main process
need to kill one its child process. The child process
is playing a music using :
system("cat phrase3.wav > /dev/dsp ");
The main process code is (pidChild is correst) :
kill(SIGKILL, pidChild);
I tried with SIGUSR2 (with a function associated to
the SIGUSR2 signal) : same result.
The opposite is working (child process sending a
SIGURS1 to its father - the father receive the signal
and call the matching function).
Does cygwin has a problem to recieve a signal when a
problem a process is busy (command system) ?

system (...) invokes a shell to execute the command you supplied as a child
process. The shell then invokes cat as a child process of its own. So what
probably happened is you killed the shell but left the cat program still
running.
