  You probably forgot import org.kde.plasma.private.volume.
  
  > We now know which ports of which sink are currently connected, right? When I take a look at my audio sink directly on the mainboard, it has one port at the back (lineout) and one at the front (headphones). I can switch between them in the KCM, which only changes the volume, but not the direction. I.e. when I have connected headphones I cannot change here to the port on the back, the sound will still come via the front port and the back port is marked as not available. When I manually disconnect the headphone, it switches to the back again. So is there a way to change this behaviour?
  
  You can probably change it, but only in pulseaudio configuration (most likely changing some modules properties or loading/unlading modules). You can't do that with plasma-pa.
  
  > To know if a device is currently "connected", we would need to loop over all its port and check if atleast one of them is connected, right? But what about the "State" property of a sink? It seems to also indicate, if the device is currently used. Should we use this one instead?
  
  Correct, it indicates if you have "jack" connected in port. `State` property of Device is different thing, it indicates whether the device is currently playing any audio (if it has some streams, if the streams are currently playing or not).
