pulse: use the EnumFormat param to set reasonable defaults

Browse source 
Before the node is started, we don't get a Format parameters and we
don't know the channelmap of the node. This forces us to invent a
channelmap that might be wrong. We can do better by using the
EnumFormat param to extract some defaults for the format, rate and
channelmap. Fixes wrong channels in gnome-control-center when testing
speakers.
