    VolumeMenu: read output and input if PulseAudio is already ready when constructing
    
    Previously we would only read the default sink and default source when
    the connection to PulseAudio succeded. This worked because all VolumeMenu
    users where initialized synchronously during shell load.
    With the recent session mode changes though, the lock screen menu is
    created on demand, and when it loads PA is already connected, so
    it doesn't update the sliders.
