Does anyone have a demo to show that the pulseaudio.exe can ever work?
 I would prefer python about pygst, but any other language is ok.

If I just use package from cygwin mirrors, I will get the following
error. I rebased many times,it does not work.

0 [unknown (0x2F04)] python2.7 2144 child_copy: loaded dll data write
copy failed, 0x36402000..0x36402044, done 0, windows pid 5768, Win32
error 487

The pulseaudio.exe is always running even when I close the Cygwin/X
and Cygwin.(I can use ps and kill -9 pid or just use windows Task
Manager to shutdown it). Every time I start Cygwin and run a pygst, a
new pulseaudio is spawned. After several times, there will be many
pulseaudio.exe in windows background.

It plays mp4 well, because I install gstreamer0.10-plugins-ffmpeg from
cygwinports.org. The package from cygwin mirrors cannot do that.

I am willing to try something to solve this problem. I would be glad
to make contribution to pulseaudio package if possible. Any suggestion
would be appreciated. Thanks.
