The HDMI port (imx-hdmi-soc-audio) or the analog port (sgtl5000) on the Wandboard? If you are indeed using the HDMI audio, could you try using the analog audio and see if the problem persists? I reproduced the 'Illegal instruction' crashes you mention when using HDMI audio -- not only with `pulsesink' but also with `alsasink' depending on other unrelated particularities of the test-- but the problem disappeared as soon as I switched to the sgtl5000 audio. Kind regards, Marco.
