[PD] ALSA "broken pipe" on pd-extended on Beaglebone?

Hi all,
I am currently working on an embedded device made up of some hardware,
Arduino, Beaglebone running Debian white with audio cape. I am attaching a
pd file that works on a laptop. For the beaglebone, basically I change the
serial port argument to "4" for [comport] but get a "Broken Pipe" error

*ALSA input error (restart failed): Broken piperestarting input device from
state 2ALSA output error (restart failed): Broken pipe*
But ALSA seems to be working okay as long as only 1  application tries to
use it. I followed most of the directions here to get it working (
http://www.csounds.com/journal/issue18/beagle_pi.html and
http://puredata.info/docs/embedded/bbb/) I installed pd-extended by adding
the repository to /etc/apt/sources.list with directions from here (
http://puredata.info/docs/faq/debian). I know sound is okay: speaker-test
works ok. pd-extended works including sound, at least for a simple patch
(also attached).  Jack is not installed (doesn't seem necessary for single
headless instance of pd-extended).

Hmm...any help would be greatly appreciated!
