There are two audio jacks on the device, one for Line-in and the other for Line-out.

Audio over these jacks is supported through Realtek ALC3277 (RT5660) audio codec connected to the Processor/SoC over I2C. While the kernel already has the driver for the Codec, we still need a machine driver to connect audio FrontEnds provided by the Codec to the Intel SST Audio BackEnds.
