Confirmed the xfce4-mixer dependency issue. I installed gstreamer-plugins-good/bad/ugly (and dependencies), then installed and launched parole only for it to update the gstreamer registry and now mixer sees pulseaudio: http://www.zimagez.com/zimage/screenshot-11162012-062434pm.php
So when I track down which package is required xfce4-mixer dependencies need to be updated.
