I think modern Intel chips contain Tensilica Xtensa HiFi DSP [0] cores for audio processing, I’m pretty sure this is what SOF targets. I’m not an expert, but probably used for speaker DSP as well as mic/speech processing (think for Cortana/etc). Manufacturers of laptops probably provide their own firmware to load onto these cores as part of a driver.
