Hi Pierre-Louis, Mark > We cannot change the Maxim amplifier driver, it's used in a variety of > usages and platforms, and there's no reason to create a fake capture dai > just to reflect the use of a capture stream on the CPU side on some > Chromebooks. Why cannot ?? There is no effect to user if Maxim driver has full channel setting same as dammy DAI. It will be handled together with CPU, and system gets CPU channels as-is. > I don't disagree that the unconditional use of dpcm_capture isn't very > elegant, but it is what it is.

I can understand that it was working in long years, but it is working with wrong settings. So justify a wrong-settings is not good idea for me. And I don't think it is stricter criteria, it becomes *sane* criteria, IMO. Because it was working with wrong-settings, we need to makes it sane. This is the reason why it has grace time.
