Look inside the jack whit a flash light somtime there can be lint you can pop them out whit a pin. Be careful and be sure the device is off becouse there is enough current that you can die from ventricular fibrillation within 24 hours.My 3.5mm jack has stopped working on my am3e module... Both of the balanced Jack's still work fine. Wondering whether dirt or something got in and is causing it to not work? Anyone have some advice on how to proceed?
I had this a few time on my phones 3.5 jack and charging socket. If there is nothing in i i would say its death. You can also cleannit a whit a ear rod dipped in alcohol when you squish them they fit in the 3.5 socket
