Thanks!

I have checked those files and found that device is in the table and
pretty much properly defined ACPI I2C slave.

The change in the driver you referred to makes the change to modalias.

Thus, I'm suspecting that your user space helper either has some hard
coded values for previous case, or just broken.

Can you also check is the codec module loaded (lsmod) and, if it's not,
load it manually and check if sound works again.

P.S. In any case you need the patch mentioned in bug #196397
