Hi, 820-3320-B with no audio on speakers or earphones. Prohibition symbol on audio when trying to change volume. Mic isn't working either. No signs of water damage. No chime.

Any history available?
Is the audio codec recognized in System Report?

 

[Sr. Robot]

No history, codec not recognized.

Check all power rails of U6201.
Start checking U6200 output.

Done, U6200 was ripped from its pads. Thank you very much.
