You've got a 5 pins headphone connector? how does that work?

anyway, to install a switch, you'll have to cut some wiring. basically, you'll cut the L en R headphone wires, and install a stereo switch that switches the L en R wires between headphone and prosound connection.

I meant the "switch" wich mute the speaker when you insert a heaphone in the original socket. I only know that the white wire controls this, but how do I wire this to my pro sound socket without cutting? Thank you anyway

This is my connector:
