Hi David,

In 4.0 with hcid and the plugins there is only one object path  
hierarchy and a single object path per remote device (created by  
CreateDevice or CreatePairedDevice). These paths have some generic  
name plus the remote address and I don't remember right now how it  
looks like. Try out those Create*Device methods and find out :)

No. In 4.x only one method call is needed to set up a new device.  
Calling CreateDevice or CreatePairedDevice will cause hcid to perform  
SDP discovery and if it finds audio profiles a callback will be fired  
into the audio plugin which in turn will register the necessary audio  
specific D-Bus interfaces for the new device object.

Any API docs outside of the doc/ subdirectory are obsolete. You can  
find the 4.x audio API in doc/audio-api.txt
