Driver for the PS Vita Audio CODEC chip.

The original PS Vita models and all PSTV models use a Wolfson Microelectronics WM1803 while late PS Vita Slim models (e.g. a USS-1002 unit from October 2015) use a Conexant CX20902.

The WM1803 is potentially derived from the WM8962B as the pinout and registers seem to match.

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 always uses the former whilst PS Vita uses the latter if SceSysStateMgr's AU_CODEC_IC_CONEXANT check evaluates to true.
