Hello list,

I have trouble with automatically choosing audio devices because the list of available device is not the same each time I launch pd. 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. When I launch pd, the list of available device for portaudio is not the same each time... that makes difficult to choose pulse automatically. Is there anything I can do to be sure of choosing the good device? Here is an output of 3 different launchs:

running after boot:
