3- Pd 0.45 is complaining about "ALSA input_error (snd_pcm_open): no such file & directory, but it still works making noise and all. What does it mean, how do I fix it?
It means what it says. The RPi has no audio input and thus there is no ALSA input device. Pd complains about it, because by default it tries to open both input and output.
Probably you can get rid of the error with the flag -noadc.
