Soldering a wire cable plug to circuit board?

My audio interface has a headphone plug soldered directly to the circuit board. Over time it has worn out, and there's an intermittent circuit when the plug is wiggled, and is unreliable. I will bring this wire out of the box to a TRS plug dongle. I am just looking for some simple beginner advice to solder a wire onto the circuit board in place of the plug itself, hoping to get the best contact possible.

I would just replace the jack with another pcb mount jack. Digi-key or mouser should have something that will work for this....

I am fairly sure that the problem is the connection of the mount to the pcb, not the mount itself, but I want to prevent this from happening again.

Maybe someone can refresh my memory, if the wire and the pcb trace don't make direct contact (only via solder) is that acceptable?

if its mechanically sound.

IMHO the connector probably needs to be replaced because its probably cracked somewhere, but I've seen poor soldering at jacks before too, and in those cases, glueing the connector on the top side and soldering the bottom side properly fixes the issue.

Well there was no problems with the solder or pcb, so I went ahead and made a wire-out directly from it. Much happier now that I won't worry about forcing the plug.
