Thank you for your bug. What audiosink is configured to gstreamer- properties? Could you remove the applet from your panel, run /usr/lib /gnome-applets/mixer_applet2 from a command line, add the applet to the panel (it will use the instance waiting on the command line), and note if there is any error printed?
