The CoolStar SST Audio driver is a custom driver package developed by CoolStar that enables functional audio on devices that the default Windows drivers do not support. It primarily targets on Intel Skylake, Kaby Lake, Apollo Lake, Gemini Lake, Comet Lake, and newer platforms frequently found in low-cost devices and converted Chromebooks.
Never install a driver meant for Gemini Lake on a Jasper Lake device.
Some users have reported that while audio works perfectly in most applications, it stutters or cuts out during video calls in programs like Zoom. This may be related to the driver's fixed output format of 16-bit, 48000 Hz, which some applications may not handle optimally. Unfortunately, there is no universal fix, but users are advised to ensure they have the latest driver version and check for updates to the problematic application.
