Driver for the Audio CODEC chip. The original models use a Wolfson Microelectronics WM1803 while late Slim models (a USS-1002 unit from October 2015) use a Conexant CX20902.

Module

This module only exists in Non-Secure world.

The module can be found in two versions at the following locations:

os0:kd/codec.skprx / bootimage:codec.skprx for the WM chip
bootimage:codec_cx.skprx for the Conexant chip

PSTV (Dolce) always uses the former.

PSVita only uses the latter if SysStateMgr's AU_CODEC_IC_CONEXANT check evaluates to true.
