    volume: Fix initial visibility of input
    
    Currently the visibility of input volume is only updated when a stream
    is added/removed - apparently no one noticed until now, as in the normal
    user session we get away with this as long as we have some startup sound,
    but this is not the case in the lock screen, so we may end up showing
    input volume incorrectly.
