gst-libs/gst/play/play.c: Moving volume in the audio thread for instantaneous volume...

Original commit message from CVS:
2004-02-02  Julien MOUTTE  <julien@moutte.net>

* gst-libs/gst/play/play.c: (gst_play_pipeline_setup),
(gst_play_set_audio_sink): Moving volume in the audio thread for
instantaneous volume change. Maybe i will add another volume in front
of visualization later, not sure yet though.
