Bug#964582: pulseaudio-module-bluetooth: paired Bluetooth audio device (Sony WI-1000X) does not appear as audio sink

[Giovanni Mascellani]

Package: pulseaudio-module-bluetooth
Version: 13.99.1-1
Severity: normal

Hi,

I am currently having troubles with pairing my Bluetooth headset (Sony
WI-1000X) to my Debian unstable system. The Bluetooth pairing and
connection works properly: I can see the headset from the Gnome settings
application and cannot connect to it. The Gnome settings Bluetooth panel
also recognizes it as an audio device (it shows the headset icon), but
the headset does not appear in the Audio panel.

The Bluetooth connection seems ok:

> $ hcitool con
> Connections:
> 	< LE 38:18:4C:16:4D:13 handle 3585 state 1 lm MASTER AUTH ENCRYPT 

I am attaching a log of a pulseaudio session (and the log of the
corresponding command line) during which the following things happen:
 * At the beginning, the headset is disconnected.
 * At some point I connect the headset. The log notices that a few
properties of the Bluetooth device have changed, but doesn't seem to
take any other action.
 * I manually load the module-bluez5-device module with the command:
> $ pacmd load-module module-bluez5-device path=/org/bluez/hci0/dev_38_18_4C_16_4D_13
which I hope to be correct. The pulseaudio log prints something about
the device, but both the log and the subsequent "pacmd ls" command say
that profiles "headset_head_unit" and "a2dp_sink" are unavailable. Only
"off" is available, hardly of any use to listen to music.
 * Nothing changes after I try to force a2dp with the command
> $ pacmd set-card-profile bluez_card.38_18_4C_16_4D_13 a2dp_sink

The same device works properly with my Android-based phone.

I am totally willing to do further diagnosis if you help me
understanding what to look at.

Thanks, Giovanni.
