    osx: fix muted volume on startup (bgo#660012)
    
    This commit fixes a bug in the libbanshee library, which did not set the
    initial current_volume. As a result, the volume returned by
    bp_get_volume () will always be 0 until one modifies/sets a new volume
    via the volume slider.
    
    This bug also manifests itself on Linux, but the
    volume would slider get set to the right value once you start playing a
    track.
