[PD] Pd sometimes not outputting sound when launched on boot

[Dan Wilcox]

This is usually due to Pd starting up too quickly with -nogui and not setting up the audio in time.

I assume you're using a loading to turn on DSP in the patch, try adding a delay ala:

[loadbang]
|
[delay 100]
|
[ pd dsp 1; <
