Alc271x Datasheet |link| -

If you are performing a board-level repair, check the VREF pins. If the reference voltage is missing, the chip won't output sound even if the software looks perfect.

Small QFN-48 (Quad Flat No-lead), which minimizes board space.

The ALC271X series (including variations like the ALC271X-GR) is a multi-channel HD audio codec designed specifically for mobile computing platforms. It acts as the bridge between your system's operating system (via the HD Audio bus controller) and the physical audio components, such as speakers, microphones, and headphones.
