In terms of AUDIO.
LOADER
In Digital In mode, SPDIF signal goes into MPEG (ES8391).
DVD Engine
In AUX ½, TUNER mode, Analog Audio signal goes into A/DC (CS5345) and converted I2S signal and goes to
MPEG (ES8391).
SATAI I/F
CVBS
MPEG (ES8391) outputs I2S and it goes into DSP (CS48540) and Equalized and it goes into PWM (PS9829B).
