Yes, sbc was installed already. A re-installation didn't help.

The problem could be solved in another way. After re-pairing did not 
take effect, I searched once again for the complete error message and I 
found a discussion [1] that showed the solution.

The ArchWiki [2] suggets to add in /etc/bluetooth/audio.conf section 
"[General]" a line "Enable=Socket" for enabling audio-streaming. This 
options seems to cause the problems I experienced (not caused by 
pulseaudio but by bluez not cooperating completely with dbus API). In 
the beginning there were two lines in my conf: "Enable=Source" and 
"Enable=Socket". Then I removed the source-line after reading the 
article [2].

The solution is to remove "Socket" so the option is "Enable=". 
Restarting the bluetooth daemon - and the log shows just an entry for 
the succesful connection with the audio adapter.

Kind regards,
Nelson.
