Dell's laptops Inspiron 3500, Inspiron 3501, Inspiron 3505 are using
Cirrus Logic CS8409 HDA bridge with CS42L42 companion codec.
The CS8409 is a multichannel HD audio routing controller.
CS8409 includes support for four channels of digital
microphone data and two bidirectional ASPs for up to 32
channels of TDM data or 4 channels of I2S data. The CS8409 is
intended to be used with a remote companion codec that implements
high performance analog functions in close physical
proximity to the end-equipment audio port or speaker driver.
The CS42L42 is a low-power audio codec with integrated MIPI
SoundWire interface or I2C/I2S/TDM interfaces designed
for portable applications. It provides a high-dynamic range,
stereo DAC for audio playback and a mono high-dynamic-range
ADC for audio capture
