Timur, iirc your driver has some special symmetry requirement (maybe something todo with having 2 DAIs) ? I assume this is OK for you too ?Yes, that's why I was asking. I believe I'm affected by this patch as well, so I will test it. However, I never noticed a problem before, so I'm not sure what's going on.
The problem is that if the DAI is shared between two links the symmetry constraint is not applied and both links could be configured to run at different rates. Without the patch for example 'aplay -r 8000 ... & arecrod -r 16000 ...' would result in playback running twice as fast as it is supposed to.
