Hello Puredaters!
Which hardware is currently recommended for running PureData in full duplex? (input and output mono at the same time)

I've been trying for a while with a RPi+Behringer UCA222 audio interface and CCRMA, but with no luck.

I was thinking about Udoo or Beaglebone Black.
Did anyone succeed to have full duplex working with those or with any other embedded computer? Do they need an external soundcard to work?

Thank you in advance!
Cheers
Chiara
