Driver for the PS Vita Audio CODEC
Hardware
WM180xx
Fat (and PSTV?) units use the Wolfson Microelectronics WM1803E as Audio CODEC.
Early Slim units (USS-1001) are fitted with a WM1804E instead, but both ICs have the same behavior.
The driver doesn't differentiate between WM1803 and WM1804.
The WM1803 is potentially derived from the WM8962B as the pinout and registers seem to match.
CX20902
Late Slim models (e.g., USS-1002 from October 2015) use the Conexant CX20902 as Audio CODEC.
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.
