This sounds like it's setting the transfer width incorrectly, though I can't immediately see how that's changed unless the DMA driver is not working correctly. What exactly did you do to test?
I tried this on linux-samsung tree by applying all the patches from you and Lars. I initialised the dma_data for secondary dai as there is a crash with out that. Then I used aplay after running the mixer settings. ./aplay /mars/share/sounds/alsa/Front_Center.wav
Thanks Padma
