when setting the volume property on the playbin, it works for the first file,
but then, when playing subsequent files, it doesn't work

here's the log of the sound server

see, as the volume doesn't effectively get set to 0 as it should.

this is with sound-server cvs (
http://www.navsys.org/cvs/sound-server.tar.gz?view=tar )
and the command
dbus-send --system --type='method_call' --print-reply --dest='org.navsys.sound'
/org/navsys/sound/Player org.navsys.sound.Player.Mute
to request the mute.
