Re: Wiring question - Nextion case

Yes, which is normally connected to pins 5/2 of the phones jack when no plug is inserted, completing the connection to pin 7 on analog J1 connection. Inserting a plug disconnects J4 (if im observing it correctly). Mine is wired this way and I have audio to the amp with no plug in the jack and no audio to the amp/speaker with phones plugged in.
