HFP HF - Reject SCO Issue

HFP HF - Reject SCO Issue

[Jomon John]

[-- Attachment #1: Type: text/plain, Size: 921 bytes --]

Hi,

I am trying to configure HFP with Bluez(5.34), Ofono(1.17) and pulseaudio(6) on a Freescale i.MX6 board using Linux 4.1.15 kernel, the idea is to use the target board in HFP/Handsfree Unit role. The bluetooth controller is a Pluggable USB Bluetooth Dongle (0a5c:21e8 - BCM20702A0) with updated firmware.

The procedure followed is, 

* Pair & connect with the android mobile phone with the bluetoothctl 
* Enable modem and dial number using ofono test scripts

After this the call is being made but the audio routing fails with "Reject SCO : Agent not registered" message from oFono. While checking with btmon its found that the SCO Connect Request has been rejected with the reason of limited resources(0x0d).

Can anyone help me to identify the root cause, I spent a lot of time trying different version combinations, loading firmware and checking logs but still nothing.

With Regards

This looks like a problem with PulseAudio configuration. oFono does not 
handle SCO data, PulseAudio does that. In order to do that, PulseAudio 
needs to register an agent with oFono. Then the SCO socket will be 
established and the fd handed off to PulseAudio to process the audio data.

I have no idea how this is accomplished in PulseAudio.  This question is 
being asked fairly often recently.  Does PulseAudio have an 
FAQ/documentation for this yet?

In /etc/pulse/default.pa, add parameter headset=ofono to module-
bluetooth-discover. That should be all that's needed at PulseAudio
side.

Denis, would you be willing to help me with the oFono parts, if I write
a document explaining how to make bluetooth audio work with
BlueZ5+PA+oFono?

Did you load module-bluetooth-discover with headset=ofono as argument?
Normally this should be sufficient to make it work. When the connection 
is established,
pulseaudio automatically loads loopback modules for the phone. You might 
have
to check if the modules have the correct source / sink.
Additionally to observing the log files, you can debug what is going on 
by using
dbus-monitor to see the messages on the dbus.

Unfortunately there is no HowTo as far as I know. Most stuff you find on 
the net is outdated.

Hi,

Thank you for the support.

Yes, module-bluetooth-discover is loaded, also tried with "ofono" and "auto" arguments, but nothing till now.

Could you please provide further more details regrading the source sink setup.

Yup, i will share the logs.

Thanks, SCO transport is working now, even though i cant hear anything on headset sco traffic is visible via btmon during phone call.The issues were,

* The build system(Yocto) was not properly enabling the ofono backend for pulseaudio, took some time to identify this.
* Configured default.pa with proper module name name(module-bluez5-discover) and arguments
* device, module and card restore modules are causing issues, so disabled it !! 

Currently trying to change volume with alsamixer is giving following message,

    alsa-plugins-1.0.29/pulse/pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
    cannot open mixer: Connection refused

Did you check with "pacmd list-sinks" and "pacmd list-sources" if the 
bluetooth sink and source are
available? Did you check if loopback modules get loaded?
If they get loaded, please check if they are loaded correctly. There 
must be one module with source
set to your phone and sink set to your default sound device and one 
module in the other direction.
You should also see some output of the loopback modules in the 
pulseaudio log.

Thanks for the support, things are getting more and more interesting because now,

* A2DP is working fine, but i cant find bluez source or sink in pacmd or pactl outputs, but same time the loading of module loopback with bluez_source is shown in journalctl logs of pulseaudio.

    module.c: Loaded "module-loopback" (index: #28; argument: "source="bluez_source.CC_C3_EA_0A_15_90" source_dont_move="true" sink_input_properties="media.role=music"").

* Same for HFP, nothing related to bluez_* in pactl or pacmd outputs. Again i can see the audio levels changing in pavucontrol (connected from external machine with PULSE_SERVER) but only one side audio is working which is from device side mic to other end. on the other side (calling phone to device) the levels are changing but seems to be not routed to the default sink (since the levels are not changing in the default sink)

    Loaded "module-loopback" (index: #30; argument: "source="bluez_source.CC_C3_EA_0A_15_90" source_dont_move="true" sink_input_properties="media.role=phone"").
    card.c: Changed profile of card 1 "bluez_card.CC_C3_EA_0A_15_90" to headset_audio_gateway

some more information regarding the setup,

* Everything is run as root user who is member of audio and pulse groups
* PA daemon is not in system mode 
* ofono and bluez is available on dbus system bus but pulseaudio is on dbus session bus (is this the right way ??)

Please advice,

With regards,
John J

Mh, that is strange, pacmd list-sources should definitely show the bluez 
source, you can see from
the arguments of the loopback module that the source exists.

Is there only one loopback module? There should be two, one from the 
bluez source to the default sink and
one from the default source to the bluez sink.

Is this anyway related to dbus configuration or selected bus (ssystem vs session) ?

You were right, as per the logs the module-loopback loaded two times, 

     [pulseaudio] module.c: Loaded "module-loopback" (index: #41; argument: "sink="bluez_sink.CC_C3_EA_0A_15_90" sink_dont_move="true" source_output_properties="media.role=phone"")

     [pulseaudio] module.c: Loaded "module-loopback" (index: #42; argument: "source="bluez_source.CC_C3_EA_0A_15_90" source_dont_move="true" sink_input_properties="media.role=phone"").
    
The audio from default source is channeled to phone but i cant hear any output audio from phone on the board while HFP session, so is there any way to control or verify the the source sink routing during the HFP session.

With Regards,

John J

What does pacmd list-cards show? Is the bluez device listed there? Can 
you check (with pavucontrol
or in the logs) if the loopback from the phone goes to the correct sink? 
Do you see messages in the
pulseaudio debug log from both loopback modules?

As per the level changes shown in pavucontrol the audio from the other end of the phone reaching the bluez source, but level changes are not shown in the default sink, so i assume that the routing doesn't work between bluez source to default sink, also i didnt find much info about this on logs, what should i look for ?

yes, Other than the module load messages i didn't find much (oh sure, discarding all the "Could not peek into queue" and "Requesting rewind due to end of underrun" )

The loopback modules should provide messages every 10 seconds. There 
should also be
messages like

[pulseaudio] module-loopback.c: [bluez_sink.CC_C3_EA_0A_15_90] Updated sampling rate to 8000 Hz

for the other loopback. There you can see what sink is used for the 
second loopback.
Underruns or "cannot peek into queue" messages should only occur at the 
startup of the
modules but not during normal operation. Could you post the relevant 
parts of your log?

Looking at the log it seems like there is no data coming from the bluez 
sink. Is there anything
in the bluetoothd log? I've also seen that you load module-role-cork. 
Perhaps you should not
use it at the moment, it might interfere if the stream does not have the 
correct role set.

Now again 'pacmd list-cards' and other list commands doesn't shows the bluez source/sink in outputs during A2DP or HFP session, looks like something weired happening.

Thank you, removed this.

Finally a clarification question regarding bluez_sink and bluez_source, the input from default source (mic) goes to bluez_sink and output from bluez_source routed to default sink(headphone/speaker), hence the name sink input ans source output, is this right ?

Mh, this is really strange. I have no idea. Do I understand right that 
you can sometimes see them and sometimes not?
Have you tried a recent pulseaudio version?

It is rather the absence of messages in the log. You only get regular 
reports from one
loopback module. The fact that the messages from the second loopback are 
missing
shows that this module is hanging somehow. I have seen this, when the 
module does
not receive data, but there may also be another cause for it.

Personally I find the names "sink input" and "source output" somewhat 
confusing. The source output
is the connector of a stream to the source and the sink input the 
connector to the sink.
Since a sink can play back multiple streams at the same time, multiple 
sink inputs can be connected
to one sink. Likewise the signal of a source can go to multiple 
destinations, so a source can be connected
to multiple source outputs.
In your case you have:

bluez_source -> (source_output_1 -> loopback_1 -> sink_input_1) .-> 
default_sink

and

PC mic -> (source_output_2 -> loopback_2 -> sink_input_2) -> bluez_sink

where the parts within the brackets all belong to module-loopback.

It took time, but I have now completed a wiki page about bluetooth in
PulseAudio. Thanks, Denis, for your input. I still haven't tried to use
HFP with oFono myself, so it would be good if someone more experienced
could check that the oFono stuff on the wiki page at least seems
accurate.

Any suggestions for improvements are welcome, or you can also edit the
page yourself if you have write access to the freedesktop.org wiki. I
intend to keep the page up to date, and I might add some more
information later (like explain what module-bluetooth-policy does).
