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.

Wow, that's unexpected! :(
Are other audio-related things working fine?

Hello,
I got that new Raspberry Pi model 2b. It is indeed much faster than b or b+ in practice, but alarmingly, I can't get useful sound from Pd. Continuous dropouts, no matter if built-in output or USB sound card (iMic) is used. I've built puredata 0.46-2 from Raspbian jessie source, for sure it has real time prio (can verify when starting Pd with option -verbose). No clue what is going on here, so far.

Ok ... so it is a very similar chip with Quad-core ARMv7 replacing the single core ARMv6, with the rest of the chip apparently left unchanged ... so same USB and same graphics, more CPU for audio and a desktop, still less than half the price of an Udoo.
Not much docs up yet at all, but there are images for a few systems ... kind of typical.
And the move to ARMv7 takes it closer to current hardware, so for example there isn't the same need to build raspbian as a half-way house between 2 debian builds ... for now they say they are keeping the same user-space in both raspbian builds and seem to have compatibility high on their agenda.
Has anyone here actually got one yet?
