Hi Folker,

Just to double check, and to make sure the regression you're seeing is
not a combination of any additional, yet unknown side-effects, could you
perform one more test?
In dmaengine_pcm_pointer() (the function we just patched), could you
replace the call to snd_dmaengine_pcm_pointer() with
snd_dmaengine_pcm_pointer_no_residue() while keeping 7e01511443c3 active
and test if this fixes your issue or not?

I have performed the test (replace the call in dmaengine_pcm_pointer()
function of provided patch) while keeping 7e01511443c3 active.
I see issue is fixed audio is working with this.

Hi Marek,

I came to the same conclusion, that the residue handling is broken in
the xilinx DMA driver for cyclic transfers, and the fix is below, with
two extra fixes in top:

I have tested the provided patches the audio is not fixed with this.

Do you have any other patches applied on the xilinx DMA driver by any 
chance ? If yes, make sure you only test these three.
