I am afraid you will need to find how GPIOs need to be tweaked with sof_es8336 quirks to make sound work. There is a possibility that we manage to reverse engineer what Windows uses with the _DSM method, but it's only an idea at this point. It'll take a while to get Linux support for all these platforms.
