** Description changed: - 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. + [Impact] + The Dell Edge IoT Gateway is based on kabylake, and the audio codec is alc3277 + which is connected to kabylake PCH via SSP0, there is no ASoC machine driver + for this board, so the audio (line-out and line-in) can't work. + + + [Fix] + write a ASoC machine driver for this board, and this driver is based on + the existing driver kbl_rt5663_max98927.c + + + [Test Case] + play sound via line-out jack, record sound via line-in jack, all work well. + + + [Regression Potential] + Very low, this machine driver is specific to Dell Edge IoT Gateway. Only + the machine with the HID:10EC3277 in the BIOS can use this driver.
