Hi Eytan,<br>
<br>
this looks like some problem with module-null-source. Unfortunately
I will be on<br>
vacation for the next three weeks, so I cannot follow up. Maybe
someone else<br>
on the list has some idea, sorry.<br>
<br>
Regards<br>
Georg <br>

This looks fine, the messages are from two module-loopback
which are loaded to play back<br>
the audio coming from the phone and to transmit audio from
your computer to the phone.<br>
But this is also where it is getting strange because you
have no other sound device.<br>
The only sink available to play back audio to is the phone
and the only source to record from<br>
(except the phone source) is the monitor source of the phone
sink (See below for explanation<br>
of the monitor source).<br>
<br>
To avoid that situation you should add a null sink and a
null source to your system using<br>
module-null-sink and module-null-source and make them the
default sink and source.<br>
Then audio coming from the phone will be played back to the
null sink (and you can record<br>
from null.monitor) while silence coming from the null-source
is sent to the phone.

<p class="MsoNormal">Please note:<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in">I’m now familer

<p class="MsoNormal" style="text-indent:.5in">Pacmd list output

loaded and one sink.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Also, could someone explain why are there
two source available? Nexus 4 and Nexus 4 monitor?<o:p></o:p></p>
<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Times New
Roman","serif""><br>
The monitor source is created for each sink so that you have
a source from where you<br>
can record what is played back to the sink.<br>
<br>
<br>
<o:p></o:p></span></p>
<p class="MsoNormal">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.<o:p></o:p></p>
