It has a volume icon in the system, at the time of raising or lowering the volume it is gray.
I tried with another system and it has the same symptom.
change u6201 and the same.
pp4v5_audio_analog 4.45V
PP3V3_S0_AUDIO_ANALOG 3.3V
PP1V5_S0_AUDIO_DIG_FILT 1.5V
i'm thinking it may be some of the amps
but the voltages on the coils when powering up and listening to the sound of the PRAM
