using 'spd-say Hello' doesn't plays anything on my BT device.

Here it plays again on the internal speaker.

Are the settings for the state file above working for you playing 'spd- 
say Hello' without modifying the contents from that link ?

After looking into the code, is there a need for modifying the device  
respect to my neo ?

This is because I call the following python script before I start  
mplayer with bt support.

#!/usr/bin/python
import dbus
bus = dbus.SystemBus()
manager = dbus.Interface(bus.get_object('org.bluez', '/org/bluez'),  
'org.bluez.Manager')
conn = manager.ActivateService('audio')
audio = dbus.Interface(bus.get_object(conn, '/org/bluez/audio'),  
'org.bluez.audio.Manager')
path = audio.CreateDevice('00:1D:82:04:AA:40')
audio.ChangeDefaultDevice(path)
print path
sink = dbus.Interface(bus.get_object(conn, path),  
'org.bluez.audio.Sink')
sink.Connect()
