Thank's for the patch, when i put a loadbang in place of the bang in the 
pacth, the dsp don't turn on with the -nogui option.

But in fact i think the dsp cannot be turn on with a loadbang when the 
command line option -nogui option is selected because pure-data must 
wait for detecting soudncard or anythong else before turn on the dsp.
