What I would like

Music Streams have a  user set rule of always go to USB Speakers, if
the USB speakers not pugged in then follow the priority list.

Priority list is the order in which I plugged devices in.. (this is
local machine devices only)

 - Bluetooth headset
 - USB headset
 - USB speakers
 - Internal

If a device is removed it should be removed from the priority list, so
unplugging the USB headset gives

 - Bluetooth headset
 - USB speakers
 - Internal

Plugging USB headset back in gives

 - USB headset
 - Bluetooth
 - USB speakers
 - Internal

Devices which have a preferred device set should always use that
device if available, else fall back to following the priority list

I don't consider this magic from the point of view of the user.. its
fairly simple sound moves to the device I just plugged in unless I've
set up configuration to tell it not to

I don't know if we are going to agree here :)

You want the user to manually select devices, I want the user to be
able to override a sane (IMHO) default device selection behavior

I want to be able to tell my sister that all she has to do to use her
headset is "plug it in".

At the moment I have to tell her to plug the headset in.. left click
on the speaker icon, click settings, goto output tab, click the
"correct" output, now restart what ever app your using....

/end rant
