OK that's something then. I'm in the middle of some i.MX6 builds at the minute but will look at this with the meta-raspberrypi kernel later and come back to you. I suspect I will see the same as you. I don't have anything capable of HDMI audio about here so will output a wav file or something to the analogue jack. What's your simplest test case? I might also have a look and see if I can get anything out of the GStreamer1.0 audio/video playback as I'm looking at that too at the minute.
