pulse: update per channel volumes

Browse source 
Use the channelVolume property to update the individual channel
volumes.
Update property values to match pulseaudio.

Handle the case where the number of channels changes. In pulse this
can normally never happen. Emit a remove and add of the node when
this happens as to not confuse pulse clients.
