820-3662 no audio on headphone jack

[dudipupan]

Hey,
i'm working on a Macbook Pro mid 2014 15" that came with no audio. Located a partial short on PP4V5_AUDIO_ANALOG, caused by U6201.
After replacing U6201 I got sound again with speakers but when i connect headphones to the audio jack i just get some deep "clicking noises" but no sound at all...
The macbook detects the headphones (in die sound settings).

Thank you

Is U6200 still good?

Yes, u6200 is good. After replacing U6201 and noticing the Jack problem I replaced it.

Headphones amplifier is embedded into U6201; try another chip.
