[pulseaudio-discuss] Bluetooth devices no longer detected after upgrade from 2.0 to 4.0

[Georg Chini]

Hello,

after upgrading to Pulseaudio 4.0 my bluetooth devices (headset, 2 mobiles)
are no longer discovered. I am running Debian unstable on an amd64 CPU,
the new Debian package was released a few days ago.
I also filed a bug with Debian but did not receive a reply so far. To 
make sure
this is not a problem of the package I compiled pulse from GIT.
I also made sure, that that the headset is properly connected by using ALSA
to play something. This worked fine. Pulseaudio 2.0 discovered the devices
when I connected them. Running Pulse with debug output gives slightly
different results, if "Media" is enabled in Bluez or not. Bluez version 
is 4.99.

With Media enabled:

During startup:

Doing the same with Media disabled:

So it seems that pulse does see the headset, but does not load 
module-bluetooth-device.
Loading the module manually does not help, pulse does not recognize that 
the headset is
connected.

I hope someone can help me to figure out what goes wrong. Anything more 
I should try?
Any config options that have changed from 2.0 to 4.0? If it is a bug, 
what can I do to find
out where the problem is?

Thanks in advance for any help.
