We are also a little suspicious that this laptop is using SSP1 for the I2S audio connection to the codec. The bad news is that the FW used by this BYT ADSP driver does not support the SSP1 port. It's hard coded to use SSP0 (Jarrko, please correct the port numbering if it's wrong). There are going to be no further releases of this FW.
That firmware is hardcoded for SSP2, i.e. 3rd port and low-pin count Baytrail packages have only 2 SSP ports. Obviously machines using those variants have to use either SSP0 or SSP1.
Please see pages 29-30 for Baytrail package differences: https://www-ssl.intel.com/content/www/us/en/processors/atom/atom-z36xxx-z37x...
