<div dir="ltr">Yup, that was it. I had to get some Freescale guys to fix some kernel code and the fixes should filter out into the various branches and repos over time. I think I'm one of two people that have functioning audio on the iMX6 platform right now. It's like having a stack of Pi's in terms of processing (no video acceleration though).</div>

</div>i did some tests with the wandboard and an external USB soundcard, and i<br>
*never* managed to get jackd running stable for "longer" (the project<br>
required that audio would work for days and weeks without restart).<br>
so i ended up using a complicated (compared to jack) plugin system based<br>
on ALSA.<br>
it turned out that the timing on the wandboard is much too imprecise for<br>
jack (and the connected cheapo USB-soundcard did not help)<br>
<br>
obviously this is not the problem you are facing here (as i did get full<br>
duplex sound), but maybe this info is of some other use...<br>
