As of 2025, Intel has largely moved to the "SoundWire" audio bus on newer platforms (Alder Lake, Raptor Lake, Meteor Lake). However, millions of devices with Apollo Lake, Gemini Lake, and Amber Lake remain in active use—especially in education, budget laptops, and x86 tablets. CoolStar continues to maintain the driver with periodic updates, including experimental support for early SoundWire devices.
If you are using a low-cost Windows tablet (Chuwi, Teclast, Onda), a 2017–2020 Dell Inspiron, or a Microsoft Surface Go 1/2, the CoolStar SST audio driver is not just a "better" option—it is often the only option that fully restores audio functionality.

Before we discuss why CoolStar’s version is better, let’s understand the problem. Intel SST (Smart Sound Technology) is an integrated audio DSP (Digital Signal Processor) found on many Intel Atom, Celeron, and Core processors (especially Apollo Lake, Gemini Lake, and Amber Lake generations).
Common issues with stock Intel SST drivers include: As of 2025, Intel has largely moved to
OEMs like Dell, HP, and Lenovo often stop updating these drivers after two years. That’s where CoolStar steps in.
For audio producers and gamers, latency is king. User benchmarks across Reddit and GitHub show that the CoolStar driver reduces DPC (Deferred Procedure Call) latency by roughly 20-30% compared to the generic Microsoft SST driver, reducing audio glitches and pops. OEMs like Dell, HP, and Lenovo often stop
While Intel drops support for older chips quickly, CoolStar maintains registry keys and inf modifications that allow the driver to work on "legacy" hardware that Microsoft marks as "unsupported."
No. It operates entirely in software within the Intel SST specification. At worst, it will fail to install. It does not overvolt or flash firmware.
The stock driver might disable the headphone jack when the microphone array is active. CoolStar’s driver restores full jack detection, mic array support, and even enables stereo mix where OEMs disabled it.
