  It works the same as the dsp device under linux, so 

    fd = open ("/dev/dsp", O_RDWR); 

should work to a first approximation..... there's a testcase in the cygwin
source code that would serve as a good example, take a look here:

http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/testsuite/winsup.api/devdsp.
c?cvsroot=src

or to just download the latest version, you could run 

wget -O devdsp.c
'http://cygwin.com/cgi-bin/cvsweb.cgi/~checkout~/src/winsup/testsuite/winsup
.api/devdsp.c?rev=1.4&cvsroot=src'

at the cygwin shell prompt.

    cheers,
      DaveK
