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

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
