I just bought a Comet Lake notebook with ES8336, but I'm having a hard
time to make audio work on it.

some info about the system from dmidecode:

So far I was unable to make speaker/mic to work on it on none of the
tree modes (SOF, SST, legacy). With SST, nothing is recognized.
With legacy mode, only HDMI works. With SOF, it says sound is disabled.

On SOF mode, sof-essx8336 doesn't load (it loads instead snd_soc_es8316).
While I never played with SOF, I suspect that it is because there's 
no entry for ES8336 at soc-acpi-intel-cml-match.c nor there are any 
firmwares for CML available at upstream sof-bin tree.

Also, it currently complains about different firmware ABIs:

Any tips to make it start producing some sound?
