New bluetooth apps, but no up to date documentation: a2dp and sco with gutsy?

[doudou]

The bluetooth stack evolves fast, but I can't get the headset properly working.
Under Feisty, I could use it with a2dpd and it worked nice with amarok, skype, kaffeine (I had problems with vlc). Although it was a bit tricky to switch from a2dp to sco.
With gutsy, I can't get the a2dp and the sco services.
I'm confused and I lack of a good howto...
