Hello,

I use

* Debian Jessie/Experimental
* kernel 3.16
* pulseaudio 5.99-2
* bluez 5.27

when I connect my Android4.4-based smartphone to PC via bluetooth, I get A2DP
profile only, not HSP/HFP

Pulseaudio debug log contains this lines:

D: [pulseaudio] bluez5-util.c: Adapter: /org/bluez/hci0
D: [pulseaudio] bluez5-util.c: Unknown interface
org.freedesktop.DBus.Properties found, skipping
D: [pulseaudio] bluez5-util.c: Unknown interface org.bluez.MediaControl1 found,
skipping
D: [pulseaudio] backend-native.c: Bluetooth Headset Backend API support using
the native backend
D: [pulseaudio] backend-native.c: Registering Profile /Profile/HSPAGProfile

then there is no message from backend-native.c source even I connect my
smartphone.

Bluez debug log contains follow info after pulseaudio started:

bluetoothd[19688]: src/profile.c:ext_device_probe() Headset Voice gateway
probed with UUID 00001108-0000-1000-8000-00805f9b34fb

bluetoothd[19688]: src/attrib-server.c:attrib_db_update() handle=0x0008

then, when I connect my smartphone, bluez writes this:

bluetoothd[19688]: src/device.c:connect_profiles()
/org/bluez/hci0/dev_00_02_5B_00_13_5B (all), client :1.206

gateway Host is down (112)
bluetoothd[19688]: src/device.c:device_profile_connected() returning response
to :1.206

But with ofono backend (without any other changes), my smartphone connects via
HSP/HFP and can use PC as headset device perfectly.
