At the moment I am working only on the raspberry and I have worked out a<br>
correct gstreamer pipeline to be used, which is the following:<br>
<br>
gst-launch-0.10 alsasrc device=hw:1,0 ! audioconvert ! audioresample !<br>
alsasink<br>
<br>
Anyway, when I use the ROS package audio_common (<br>
<href="<a href="http://wiki.ros.org/audio_common"" rel="noreferrer" target="_blank">http://wiki.ros.<wbr>org/audio_common"</a>;> ), in particular the<br>

I tried a lots of difference set-ups and several plugins, but since gstream<br>
is correctly working when I launch it from the command line, I am quite sure<br>
that it is due to some configuration issues.<br>
<br>
Thanks a lot in advance.<br>
