[PD] PD on Raspbian

When I was using Raspbian, I could not get duplex (simultaneous input and
output) audio unless if I set my samplerate to 32kHz. This seemed to be due
to an issue listed here: https://github.com/raspberrypi/firmware/issues/197

Using the Satellite CCRMA distro, I've been able to set it to 44.1kHz with
input and output working fine using ALSA (haven't tried JACK, but I'd
expect it to work).

Pd-extended is installed by default on the Satellite CCRMA image and it
works with my soundcard (Behringer UCG102). You can download/learn about
the distribution here: https://ccrma.stanford.edu/~eberdahl/satellite/

I do still have issues achieving a desirably low latency on pd-extended
(vanilla works slightly better), but overall things have worked much better
than on Raspbian.
