Has no one got the output of speech-dispatcher into a bouetooth

Using mplayer -ao alsa:device=bluetooth works, but not spd-say. It
always comes out of the speaker.
What does the speech-dispatcher documentation say about selecting
a sound
card for output?
I havent found anyting usefull in the documentation or in the
configuration files.
Also try some of the stuff from the wiki:
http://wiki.openmoko.org/wiki/Neo_1973_audio_subsystem#Driver_Status_3
Specifically these:
http://wiki.openmoko.org/images/3/3d/Btcpu_gta02.state.txt
http://handheldshell.com/bluetooth_pcm
http://opensource.wolfsonmicro.com/~gg/bluetooth-pcm/bluetooth_pcm.c
Usage would be something like this:
$ alsactl restore -f Btcpu_gta02.state.txt
$ ./bluetooth_pcm &
[play some sound here]
using 'spd-say Hello' doesn't plays anything on my BT device.
$ killall bluetooth_pcm
Here it plays again on the internal speaker.
The interesting controls of the state file are these:
20 'Sidetone Capture Volume' -> 0 (increase as needed).
64 'Capture Right Mux' -> 'Sidetone' to route playback mixer sound
into right ADC.
66 'Capture Right Mixer' -> 'Analogue Mix Right' to record right
channel
from right ADC.
67 'Capture Left Mixer' -> 'Analogue Mix Right' to record left channel
also from right ADC.
68 'Playback Mixer Voice Capture Sw' -> false to not mix GSM output
into the
sidetone.
69 'Playback Mixer Left Capture Swi' -> true to mix left output into
the
sidetone.
70 'Playback Mixer Right Capture Sw' -> true to mix right output
into the
sidetone.
(Maybe look at control 22 'Capture Volume' too?)
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()
