I have a new T470. From the Specs I can see it´s equipped with 4 pole, 3.5mm (TRRS) jack combo.
I tried to plug old/basic earphones and it seems they are not recognized at all, sound continues to come out of laptop speakers.
Side note, earphones work fine on phones, they are 4 pole, 3.5mm as per picture.
Any hint on what´s the problem? Thanks!
