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!

Alsa is only supposed to work with One application at a Time.

I am only using it with one app with is pd-extended.

Hi,
more precisely, The number of simultaneous audio streams (called an application in your message) depends on the soundcard hardware mixer and the driver.
In the case of the BeagleBone, this probably sums as 1 hardware mixer == 1 application at a time.
Cheers, Charles

Well, the follow up to this is that I was able to resolve the problem by installing pure data (Vanilla), pd-cyclone, pd-comport with apt-get. Added /usr/lib/pd/extra/cyclone to the search path (-lib cyclone didn't work for some reason). And it works!
I wonder if that means there's something wrong with pd-extended (which seems to be rather recently ported to ARM)?
best, Dave
