Part 1: Understanding Intel SST Audio – The Root of the Problem

What is Intel SST (Smart Sound Technology)?

Intel Smart Sound Technology (SST) is an integrated audio DSP (Digital Signal Processor) built into select Intel chipsets and SoCs (Systems on a Chip), particularly those in the Apollo Lake, Gemini Lake, and newer low-power families. Unlike traditional audio codecs, SST offloads audio processing tasks from the main CPU to a dedicated low-power DSP, improving battery life and enabling voice wake-up features (e.g., "Hey Cortana"). The CoolStar SST Audio (WDM) driver enables sound
