MSi GP63 Leopard 8RF no audio in speakres

[Dino550]

Hi,

I got a problem with audio in my laptop, driver is properly finding and install devices, audio work full correctly in headphones by jack. But w/o the jack in laptop the regulator volume level work (showing percent the volume level) but in speakres is silent. I'm changed the speakers and codec on motherboard (ALC1306) on new but is all time the same issue. Motherboard in MS-16P51

Please help me to with find the issue!

Investigate the headphone jack. Ran into a similar fault with a macbook where the client damaged the tip of the headphone cable inside the headphone jack.

Now the logic board believes that only the headphone jack sould be active.

For the macbook, the logic board is really old (A1278 I believe) and the connector is rare to find but Aliexpress sells donor boards with this same connector.

Found a youtube video for the macbook that shows how to bypass the tip connect pins so that the logic board believes that the internal speakers should be active.

Summary - I believe that you have a defective headphone jack where the contacts are no longer mating when the headphone cable is removed. For this reason, the internal speakers are not working.

Post clear pics of the solder side of the headphone connector on this logic board - perhaps you can find a good replacement on Aliexpress.

Ok, it is possible issue but do You have any cloue how to find the jack detecion? So if I undersnad You corrctly, when plug in the jakc to socket the electronic identifies it and change audio from internal speakers to eg. headphones

I of course have got the schematic and the signal from jack socke go to muliplexer but I don't know how the electronic identifies the inserted jack plug?

Schematic and socket below
