I confirm it is the culprit.

Does this mean that PCM3168s codec works fine on imx7 using SAI on
4.9.x plus the revert?

And there is already a fix for this in 4.10:
85f57752b33c (dmaengine: imx-sdma - correct the dma transfer residue
calculation)

This fixes audio output on i.MX6 and should probably be sent to -stable.
Can you see if applying this patch gets rid of the issues on i.MX7?

It does too, thanks!
It is probably worth having it on 4.9.

Hi,
   Thanks for mention the problem and confirm that the above patch fixed 
the issue.

I'm a bit surprised about the issue that Stefan mention, which in his 
case was a "noise". In my case was more like a sound interruption (I was 
testing on a iMX6).

But good to hear that works :)

Regards,
    Nandor
