Bluetooth connection to device not working

Hi,

with the bluetooth-applet in the systray i tried to connect to an audio-device. But the Connection failed every time …

The i checked it in the terminal with hcitool.

Trusted: yes
Blocked: no
Connected: no
LegacyPairing: no
UUID: Audio Sink (0000110b-0000-1000-8000-00805f9b34fb)

but to connect with

connect 00:15:71:12:4A:CE

doesn’t work either

and i don’t get any further info, why it failed.

What can i do to get a connection?

Ciao!

Dieter

Do other bluetooth devices fail to connect aswell or only audio devices?
Is the package pulseaudio-module-bluetooth installed?
