Right click on sound applet in gnome panel -> Click on Sound
Preferences -> Click on applications. This should show which
applications are using pulseaudio.

If that still doesn't help then open a terminal window and type
lsof | grep snd
This will give you a list of programs accessing the snd device. You
might need to install the lsof package.
