Hi Georg,
Thanks for your reply.
I tried to do what you suggested:
1) I loaded module-null-sink
2) I loaded module-null-source
3) Both of them are defined as default.
4) I try record by ‘parecord -rv --device=null.monitor /pulse/rec’
After answering the call, I get the following assert:
( 121.424| 0.012) E: [null-source][pulsecore/memblockq.c:286
pa_memblockq_push()] Assertion 'uchunk->index + uchunk->length <=
pa_memblock_get_length(uchunk->memblock)' failed at pulsecore/memblockq.c:286,
function pa_memblockq_push(). Aborting.
Larger log and is attached.
‘pacmd list’ before answering is also attached. – seems good to me.
Do you have any hint about what could be the cause?
Thanks, Eytan.

Hi,
I’m trying to enable HFP on pulseaudio 6.0 using oFono and bluez 5 on a new
embedded platform which doesn’t support alsa yet.
In order to confirm that audio is ‘played’ I record it using parecord tool. –
This method worked just fine when enabled a2dp a short time ago.
After executing oFono & pulseaudio, a call is answered on the remote device- It
is seemed that the relevant profile is chosen on pulseaudio, and parecord fails
to record.
What is the source you are recording from?
When executing ‘pacmd stat’ it seems that
Memory blocks allocated during the whole lifetime: 192, size: 699.9 KiB.
Is constant while pulseaudio prints to terminal the following message along the
call with relatively fixed intervals:

This looks fine, the messages are from two module-loopback which are loaded to
play back
the audio coming from the phone and to transmit audio from your computer to the
phone.
But this is also where it is getting strange because you have no other sound
device.
The only sink available to play back audio to is the phone and the only source
to record from
(except the phone source) is the monitor source of the phone sink (See below
for explanation
of the monitor source).
To avoid that situation you should add a null sink and a null source to your
system using
module-null-sink and module-null-source and make them the default sink and
source.
Then audio coming from the phone will be played back to the null sink (and you
can record
from null.monitor) while silence coming from the null-source is sent to the
phone.
Please note:
I’m now familer with oFono at all – I simply run it as ofonod -d
Pacmd list output is attached while call is still ongoing. – there are 2
sources loaded and one sink.
Also, could someone explain why are there two source available? Nexus 4 and
Nexus 4 monitor?
The monitor source is created for each sink so that you have a source from
where you
can record what is played back to the sink.
How can I confirm that the audio arrives at pulseaudio? By the log I would
assume that the answer is positive, but according to ‘pacmd stat’ the value it
seems not.
In general it looks like your setup is working.
Thanks for your help,
Eytan.
