First, a common misconception: The Realtek ALC3287 is not a traditional, standalone CPU-attached audio chip. It is a Smart Audio Codec commonly found on modern laptops using Intel Tiger Lake, Alder Lake, and newer mobile processors.
Unlike older HD Audio codecs (like the ALC295 or ALC1220), the ALC3287 is tightly integrated with the Intel Host Signal Controller (Intel SST, or SoundWire). This means that if you simply download a generic "Realtek HD Audio Driver" from the web, it likely will not work for the ALC3287.
The chip itself is capable, but without the right driver package, you lose:
Realtek doesn’t make this driver easy to find on their public site. Instead, it’s distributed through OEMs (Dell Command Update, Lenovo Vantage, HP Support Assistant) or Windows Update. That leads to a common problem: users often run generic Microsoft HD Audio drivers, missing key features.
Most users should not update this driver manually. The ALC3287 is extremely sensitive to OS updates (Windows 11 22H2 to 23H2 broke this for many Lenovo users).
