Yes, we're aware of this design and we've tried to help. There's a
series of devices based on this I2C/I2S device, which is the exception
to the rule that all Windows-based designs are based on HDaudio or
SoundWire. Intel wasn't informed of this device so we we've added quirks
device after device, as bug reports came in.

The CometLake enablement is tracked at
https://github.com/thesofproject/linux/issues/3248

I will upstream the two quirks for CometLake later today.

The latest hacky recipe to get the driver to probe is at
https://github.com/thesofproject/linux/pull/3107

There is still work to do for the 'topology' part. The comment
https://github.com/thesofproject/linux/issues/3248#issuecomment-959573378 has
a tar file with 3 possible options for the I2S/SSP connection.

The remaining part will be the codec driver, which is problematic for
now, we're still waiting for updates from the vendor and it's unclear
if/when they will be submitted.

Hope this helps
-Pierre
