[pulseaudio-discuss] pulseaudio-discuss Digest, Vol 8, Issue 12

Tue Dec 20 22:17:52 PST 2011

Thanks Frederic. I pulled the sources from git. The issue was resolved
on x86 machine.

When I used the same patches for my IMX53 evaluation board(QSB), it didnt work.
I get "bt_audio_service_open: connect() failed: Connection refused
(111)" error.
Pulseaudio fails to load module-bluetooth-device module. The bluetooth
socket creation fails and hence the module is not loaded.
I have attached the bluez, ofono and pulseaudio log.

My configuration on IMX53
1. pulseaudio - latest from the git
2. Bluez - latest from the git
3. ofono - latest from the git.

Hello All,
I am currently trying to connect my cellphone to desktop in handsfree mode.
The phone gets connected perfectly with the help of ofono.
To listen and speak I am using pulseaudio-1.0 which I patched by
referring the Frédéric Dalleau patch from
http://www.mail-archive.com/pulseaudio-discuss@lists.freedesktop.org/msg01417.html

Following scenario results into disconnect of phone from handsfree-mode:-
1) Pulseaudio started in debug mode.
2) Ofono started in debug mode.
3) Bluez 4.95 is already running.
4) When I connect phone with the help of Ofono in handsfree-mode it
gets connected.
5) Then I do a outgoing call and load a module loopback.
6) I am able to hear voice and talk as well.
7) When I disconnect the call, immediately phone also gets
disconnected from handsfree-mode.

Please find attached pulseaudio and ofono logs.
Please provide inputs.

Regards,
Vinod
