[pulseaudio-discuss] Making phonon/kde work nicely with pulse

Hi Lennart,

OK, so attached should be a screenie of the KDE settings window.

As you can see, the idea is to list all the various detected h/w and 
allow them to be prioritised accordingly. The categories are shown on 
the left hand side, but each once shows the same set of "devices" 
(albeit potentially in different orders!)

As is clear it does show some devices that are not currently 

So to make this work nicely with pulse, I'd need to be able to:
  1. Record the sinks seen and know whether they are currently alive or 
not (e.g. for USB, bluetooth and network sinks).
  2. Provide a way to prioritise our sinks in a list. If the most 
preferred sink is not available (and our stream is not specifically 
playing on a given sink) it should automatically pick the next device 
with the highest priority.
  3. Allow this priority list to be different for different 
  3. Find a way to have something at the phonon side control the routing 
decisions in PA (e.g. by uploading rules etc)

What do you think is needed and what should I work on to get there? Do 
you see any major roadblocks?
