Hello list,<br>
<br>
I have trouble with automatically choosing audio devices because the
list of available device is not the same each time I launch pd.<br>
I am on ubuntu 12.04 / pd 0.44.3. I want to use portaudio with the
"pulse" device because I'm running another software in parallel,
that can only use pulse for playing sound.<br>
When I launch pd, the list of available device for portaudio is not
the same each time... that makes difficult to choose pulse
automatically.<br>
Is there anything I can do to be sure of choosing the good device?<br>
Here is an output of 3 different launchs:<br>

running after boot:<br>
