Aplay can play a .wav file without trouble, so it is not a general problem with the audio hardware or drivers on Pi 2b.
I installed command htop to see CPU load per core. It's interesting, the load switches from one core to another, and sometimes they all seem to be almost idle even with a heavy Pd patch running.
