[pulseaudio-discuss] Bluetooth headset pairs but doesn't create audio device

[Alessandro Crismani]

Hi everybody,

I have upgraded to pulseaudio 2.0 through Arch Linux's repository and my 
bluetooth headset is giving me trouble. I've also tried git master, with 
same results.

Particularly, when I pair the headset it doesn't create an audio device 
under Gnome's sound settings menu, hence I cannot route sounds to the 
headset. Note that pairing succeeds, given that I can play/pause music 
using the play button on the headset, but music comes from the laptop as 
I can't select the headset anymore.

This happens randomly, some times the audio sink is created and 
everything works, some times the audio sinks is not there. Relevant log 
entries when it fails the first time are:

audio service

I have added: Enable=Socket in /etc/bluetooth/audio.conf but it didn't 
solve things.

I have opened a bug at https://bugs.freedesktop.org/show_bug.cgi?id=49974
but the report is silent, so I decided to try asking here hoping for 
more feedback! I'd love to provide more information, but I do not know 
how to proceed further.

Cheers,
Alessandro
