Yes, it's better to try and use GitHub to attach logs and results.

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.
