switching automatically to headset speaker when connecting bluetooth headset

Opensuse 13.1 x86_64
kde 4.14

i assume headset is paired and connected with bluedevil tool

go to kde settings
launch “Multimedia” tool
go to “sound and video settings”
go to “audio output”

for “audio output”, notifications, music, video, communication, games, accessibility
put <name of the headset> at the higher place

note : it seems that phonon rules is : use the first activate output device in the list

If this is not automatically done by default, I wonder if this shouldn’t also be submitted as a bug at https://bugzilla.opensuse.org?
IMO auto switching to a plugged in audio output device over regular speakers should be the default behavior.
