No bluez device after pactl list sources short

No bluez device after pactl list sources short

I am using pulseaudio on a raspberry debian (wheezy) but my bt-headset does not show up in sources or sinks.
What I did:
I followed the Raspbian Wheezy Installation Guide at http://kmonkey711.blogspot.de/2012/12/a2dp-audio-on-raspberry-pi.html
Having entered
pactl list sources short
I only get
0       alsa_output.platform-bcm2835_AUD0.0.analog-stereo.monitor       module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
but no bluez device.
Instead of
bluez-simple-agent
I used
hcitool scan
which showed my device.
bluez-test-device trusted <MAC> yes
worked aswell but still no bt-devices.
