<pre wrap="">Moin,
my new project seems to be easy, but the setup still does not work. On a
Raspberry Pi (raspbian jessie with backports) runs pulseaudio 7.1.2 on a
USB sound card. On a notebook I installed ubuntu xenial with Pulseaudio 8.

At least one piece of the puzzle that you didn't find is module-
loopback. That module can be used to take audio from a source and feed
it into a sink. Pavucontrol can't be used to set up loopbacks, so use
the command line:
pactl load-module module-loopback source=name-of-the-source sink=name-of-the-sink</pre>

I tried, but the pulseaudioprocess crashed.<br>

You can use "pactl list sinks" and "pactl list sources" to figure out
the sink and source names (the name is a different thing than the
description that you see in pavucontrol).

OK, to make thinks easy let us look just to one channel: bringing
the microphone on the RasPi to the loudspeaker on the notebook.<br>

Arrangement 4 (everything at the notebook end):
tunnel sink for the Pi speakers at the notebook end
tunnel source for the Pi mic at the notebook end
loopback from the tunnel source to the notebook speakers at the notebook end
loopback from the notebook mic to the tunnel sink at the notebook end

This sound good, because the setup is controled from the notebook
end. So first, <span id="result_box" class="short_text" lang="en"><span
class="">determine the device name on the RasPi:<br>
renner@lyra:~$ ssh 192.168.22.84 "pacmd list-sources | grep

<br>
The 1st entry is the monitor channel of the SignaLink card, the
3rd is the monitor of the build in card and the 2nd entry is the
microphone channel that I want to redirect. So I start the
tunnel. This work, but only for 2 or 3 seconds. For these few
seconds I see an </span></span><br>

it freeze.<br>

As soon as the loopback module is loaded pulseaudio crash. I

<p>It sound like an easy setup, but I'm going nuts :-( For the
moment I use pacat together with sox to redirect microphone and
loudspeaker, but because there is the more elegant solution with
the tunnel modules I want to use this.<br>
</p>
<p>I attached the debug output from both sides to this mail, can you
see what cause the problem?</p>
<p>Thanks</p>
