Intel Smart Sound Technology (SST)
Intel Smart Sound Technology is an on-die audio DSP built into many recent Intel laptop and tablet platforms, handling tasks such as voice wake, microphone processing, and power-efficient playback. Unlike a plain codec, it needs a matched controller driver and firmware, and a mismatch is a frequent cause of missing audio after a Windows upgrade. The validated build usually comes from the laptop or tablet maker rather than as a universal Intel download.

This coverage label describes releases discussed by this publication, not certified compatibility. Confirm the exact device or PC model, hardware revision, current Windows release, and current package requirements on the publisher source before making a change. Windows 10 Home and Pro reached end of support on October 14, 2025. Extended security updates and other editions have separate lifecycle terms; a driver listing does not extend Windows support.

The family record names Laptop or tablet maker package as the package source. Use Windows 10, Windows 11 only as reference coverage, then check the current publisher requirements for the exact model, hardware revision, Windows release, and PC configuration. A family name alone does not establish compatibility.
Shared identification, preparation, installation, verification, and rollback procedures are maintained on the full audio & sound guide, rather than repeated on every family page. The citations below follow this family’s declared vendor, system-update, PC-maker, or motherboard-maker source policy.
Official sources and citations
These links serve two different purposes. A manufacturer support selector helps you find an exact model, but does not prove that a package or feature exists for every product in a family. Claim-specific documents explain the cited technology, requirement, lifecycle, or bounded package example. In either case, check the publisher domain, exact model and hardware revision, operating-system release, supported-products list, and package notes before making a change.

Intel: Incident-specific Intel guidance that directs laptop owners to the system maker; it is not a universal SST package.
Device Driver Guide is an independent reference, not a repair or technical-support service. It does not host or mirror installers and receives no payment for these links. A named-model package example applies only to the systems and operating systems on that publisher page; it is not a recommendation to install the package across a family.
