[HELP Required]Routing Of SCO data to BT Host Speaker

[HELP Required]Routing Of SCO data to BT Host Speaker

[-- Attachment #1: Type: text/plain, Size: 1318 bytes --]

Hi,

Recently I have been trying to use Ofono to write a Handsfree based application( Using C on Ubuntu 10.10).
I am able to connect(SLC) to the AG using Ofono. After connection I am also successful in dialing to another number.
Bluetoothd indicates status as "Playing" ( SCO connection successful) once the call is established.

Problem Faced:
----------------------
However, after accepting the call I am unable to hear any voice through the speaker.

Clarification Request:
-----------------------------
1. Do I need any specific settings / configurations to be able to hear the audio?
2.Or ,Do I need to make use of any available dbus methods / interfaces to enable the audio functionality?

Please guide me on this.

current config settings :

path : /etc/ofono/modem.conf  , /usr/local/etc/ofono/modem.conf

#[hfp]
Address=A8:7E:33:AF:23:A4
Driver=hfp

path :/etc/bluetooth/audio.conf

[General]
Enable=Gateway
AutoConnect=true
HFP=true
MaxConnected=1

Regards,
Milan

You might have to loop back the PulseAudio BT source and sink to your sound card, e.g.

pactl load-module module-loopback source="alsa_input.pci-0000_00_1b.0.analog-stereo" sink="bluez_sink.78_47_1D_44_34_10"
pactl load-module module-loopback source="bluez_source.78_47_1D_44_34_10" sink="alsa_output.pci-0000_00_1b.0.analog-stereo"

You have to do this within 5 seconds after the SCO connection has been
established otherwise PulseAudio will suspend (which leads to a BT
stream stop) the streams.

Hi Daniel,

Thanks for the quick assistance.

I tried the same approach as suggested by you.

Steps:
------
1.$pacmd
2.$list-sources
( got 2 sources )

  name: <alsa_output.pci-0000_00_05.0.analog-stereo.monitor>

  (and)

  name: <alsa_input.pci-0000_00_05.0.analog-stereo>
3.$list-sinks
( got 1 sink )

name: <alsa_output.pci-0000_00_05.0.analog-stereo>

4.created a shell script "ofono.sh" with contents as below:
pactl load-module module-loopback source="alsa_input.pci-0000_00_05.0.analog-stereo" sink="bluez_sink.A8_7E_33_AF_23_A4"
pactl load-module module-loopback source="bluez_source.A8_7E_33_AF_23_A4" sink="alsa_output.pci-0000_00_05.0.analog-stereo"
(A8_7E_33_AF_23_A4 is the BT address of handset paired to the host)

5. Now I connect the host to the handset through HFP.
6.After SLC is established , I dial a number and establish a voice call.
7.As soon as the state is "Playing" ( SCO connected) , I run the "ofono.sh" ( as mentioned in step 4).

Result:
-------
I am getting the following errors:

Failure: Module initalization failed
Failure: Module initalization failed


Requesting Clarification
------------------------
1.I was wondering if any modification is required in pulseaudio configuration files to enable dynamic loading of module-loopback.( e.g "module-loading = yes" in /etc/pulse/daemon.conf ).Currently all settings are maintained as default.

2.Also, do I need to modify "SCORouting=PCM" in "audio.conf" file. (default is HCI)

It will be of great help to receive any further inputs regarding the above issue.

Best Regards,
Milan

Hi Milan,

I'm not sure if you succeeded in the mean time. 

we had a similar issue when we used the Fedora pre-installed pulseaudio 
version.

When I downloaded and compiled the latest sources it wouked in our case. 

Regards,
Andreas
