The Realtek ALC3287 is a high-definition (HD) audio codec commonly found in modern laptops, such as the Samsung Galaxy Book2 Pro 360 and various Lenovo ThinkPad models.

The "No Jack Detection" Problem on ALC3287

A notorious issue with the ALC3287 is that the 3.5mm headphone jack stops detecting headphones. The speaker works, but plugging in headphones does nothing.

Summary Table

| OS | What to actually install | Where to get it | |----|--------------------------|------------------| | Windows | OEM Realtek HD Audio driver (ALC3287 is misidentification) | Laptop manufacturer’s support site | | ChromeOS | Built into OS (do nothing) | ChromeOS update | | Linux | Kernel module + firmware | linux-firmware package, kernel 5.4+ | | macOS | Not supported | N/A |

Update ChromeOS

Instead, the ALC3287 is typically an embedded DSP / audio codec found almost exclusively in Chromebooks (e.g., Acer Spin, Lenovo IdeaPad Flex, HP x360 models using MediaTek or Qualcomm ARM chips, or older Intel Celeron Chromebooks).

Furthermore, the sourcing of the driver can be a point of confusion. Realtek provides generic drivers on their website, but Original Equipment Manufacturers (OEMs) like Dell, HP, and Lenovo often customize the driver to specifically tune the audio for their hardware acoustics. Using a generic driver on a machine optimized for a proprietary version can result in lower volume or the loss of bass response. Consequently, troubleshooting ALC3287 issues often requires navigating the delicate balance between the manufacturer’s specific stability and the newer feature sets found in generic updates.
