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. -- Alexandre Belloni, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
