Things do work in general, including the setup of the SSP engine and clocks, and when using the OSS compat layer, I can see data on the bus. With the native ALSA API, however, the DMA pointer does not move forward but is stuck at position 8. ALSA's core calls pxa2xx_pcm_pointer() a couple of times and eventually gives up on it. Unfortunately, I don't have a Zylonite board for cross-check; could anyone verify that things are not currently broken in a general way? My code base is up-to-date to sound-2.6.git/for-2.6.30. Thanks and best regards, Daniel
