Regarding this technology, I found the following document; https://01.org/blogs/2016/intel-smart-sound-technology-audio-dsp?langredirect=1. This may help since the document describes methods used in Intel® Smart Sound Technology Audio DSP products for non-HD Audio endpoints configuration performed by FW via ACPI. Now, regarding programming interfaces for this technology the best advice should be provided by the Intel® Software, and I recommend using the community support Forums.
If you have more questions, please let me know.
