I realized the problem with the dual fifo mode: it's that you had set the maxburst to 16 in your patch. I guess this must be the maxburst to a single fifo maybe? When I set the fual fifo maxburst back to 8, I get perfection again!
I actually set 16 for dual FIFO and tested with 2-channel playback. Since you have dual FIFO right now, burst 8 doesn't hurt a lot as SPBA should be a pretty dedicated bus from SDMA point of view. As long as you don't have too many SPBA modules working with SDMA. It should work for you.
