I've got a Wandboard* here for some testing and I can't get Alsa to work in duplex. Testing with arecord produces a soundfile and aplay plays it back. But starting Pd with Alsa or jack gives the dreaded errors about the resource being in use.
i did some tests with the wandboard and an external USB soundcard, and i *never* managed to get jackd running stable for "longer" (the project required that audio would work for days and weeks without restart). so i ended up using a complicated (compared to jack) plugin system based on ALSA. it turned out that the timing on the wandboard is much too imprecise for jack (and the connected cheapo USB-soundcard did not help)
obviously this is not the problem you are facing here (as i did get full duplex sound), but maybe this info is of some other use...
