820-3332 - No Sound

Liquid Damage around U6201.
I cleaned and re soldering all the U6201 pads. Also i replaced:
L6202
C6220/22/13/14
R6210


I have 5V on Pin 46
I have 3.3V on Pin 1
I have 1.5V on Pin 9

Seems the U6201 could be bad, however, i'm not sure.
Also is not recognized in the OS
Any hint?

Do you get PP4V5_AUDIO_ANALOG?
Also check HDA_RST_L.

 

[menatwork]

PP4V5_AUDIO_ANALOG = 0V

I check and replaced already:
U6200:
Pin 6 = 5V
Pin 1 = 0V
Pin 4 = 3.3 (EN)

HDA_RST_L 0V / 34K

"PP4V5_AUDIO_ANALOG = 0V"
Fix the problem; short on output?

"HDA_RST_L 0V / 34K"
Check it again, once you get PP4V5_AUDIO_ANALOG; if codec is still not recognized.
