All the solutions we suggested will not work because of a change in your
BIOS. We've only see "ESSX8336" so far and hard-coded this value, now
the BIOS writers in their infinite wisdom chose a different HID
(ESSX8326) which breaks all the existing matching.

if you can install a new kernel, please try and provide feedback on
https://github.com/thesofproject/linux/pull/3338, where I added support
for more BIOS variations of the same device. I don't have any hardware
to test so have to crowd-source the tests to the community, thanks for
your understanding if this isn't a turn-key solution.
