820-00840: Not switch to headphone jack when plugged in

[macRepairAmb]

Hello

i have a 820-00840. Original issue was no power, which i resolved by replacing U7000. Then the left speaker wasn't working, replace U6400 and left speak works now. Finally, when headphones are connected, no audio is sent to the headphones, the audio remains on the laptops speakers. I've replaced the headphone jack will cable assembly, no effect. Any suggestions as to where to start on this?

Check AUD_J1_SLEEVEDET_R level, when insert headphones.
You should note a change from speakers state.

While testing for AUD_J1_SLEEVEDET_R, at first i wasn't getting any voltage but all of a sudden i started getting voltage readings. So, i resoldered all the pins of J6600 and have full audio on the headphone jack. Thanks for pointing me in the right direction. This is now fixed.
