</span>Are you sure that wasn't using JACK via PulseAudio? What are you<br>
using GStreamer from?<br>
<br>
AFAIK, settings in GStreamer for defining the ports that the<br>
JackAudioSink connects to are new - you can set the port-pattern<br>
property.<br>

<p>You need the GStreamer JACK audio plugin, which is currently (Fall 2009)
part of the “bad” plugins collection. Most Linux distributions
make this available through their normal software install/update systems.
The name of the package containing this plugin will vary
from distribution to distribution:
on Fedora its called “gstreamer-plugins-bad-free-<wbr>extra”,
on Ubuntu its called “gst-plugins-bad”, etc. etc.</p>
</li><li>Next, you need to configure GStreamer to tell it to use this plugin
for audio output. There are 3 methods available:
<ul><li>Through the command line using gconf2 (you may need to install this
first)</li><li>Install/run gconf-editor, which is a general purpose utility
for configuring many GNOME-centric applications.</li><li>Some systems may have the gstreamer-properties command available,
which offers a graphical tool for configuring gstreamer.</li></ul>
</li><li>Your goal is set the value of:
<ul><li><code>/system/gstreamer/0.10/audio/<wbr>default/musicaudiosink</code></li><li><code>/system/gstreamer/0.10/audio/<wbr>default/audiosink</code></li></ul>
</li></ol>
<p>to this value: <code>jackaudiosink buffer-time=2000000</code>. The exact value of
<code>buffer-time</code> doesn’t matter too much, but higher values reduce
the chance of glitches/drop-outs in the audio stream. You might also
choose to set <code>/system/gstreamer/0.10/audio/<wbr>default/chataudiosink</code> to
the same value, but its less likely to be useful to you.</p>______________________________<wbr>______________________________<wbr>______________________________<wbr>_____________________<br><br></div><div class="gmail_extra">It appears neither gconf nor <code>/system/gstreamer/0.10/audio/<wbr>default/ are resident in 16.04. (I'd guess the later path .../0.10/... would not be there since 16.04 is using gstreamer 1 not 0.10, correct?<span class="HOEnZb"><font color="#888888"><br><br></font></span></code></div><span class="HOEnZb"><font color="#888888"><div class="gmail_extra"><code>Mac<br></code></div></font></span></div>
