[PD] ubuntu portaudio unstable audio device list

[Nicolas Montgermont]

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:
