Yes. But not an "official" supported way.

The Pd GUI and pd work by sending messages back and forth. You can  
listen to them by making a patch like

[r pd]

[print pd-msg]

Now open the audio pref., make your changes and see what's printed in  
the console.  Something like 'audio-dialog 0 0 0 0 2 0 0 0 0 0 0 0 2  
0 0 0 44100 50 0'. That is then the message you'd want to send to pd.  
Like

[audio-dialog 0 0 0 0 2 0 0 0 0 0 0 0 2 0 0 0 44100 50 0(
|
[s pd]

If you save the preferences (fx by sending [save-preferences( to pd)  
it will be stored in the preference file for next time you run Pd.
