Help me fix my audio decoder The pin in circle 1 has been loose

What exactly is the problem? What you describe sounds like a broken joint to me.
Just resolder the thing. Heat it up and let it cool off again.

When I wiggle the connector the entire thing (solder and pad included) go with it. It's not connected to the trace anymore.

get whoever told you what a capacitor was to show you what traces look like

then get an adult to do the dangerous soldering

>>>/diy/ohm/

it connects to the left pin labeled 2, and only the left pin, so just run a solid wire over the trace and solder at both ends. it's all 1000% obvious.

>>926152
Oh wait. The dark lines are the sides of one trace and not two separate traces, right?

I feel like a moron right now.

>>926162
Of course, you can skip the wire. Just use a sharp blade to scrape some of the green solder resist off of the trace (revealing copper) then solder the pin in question directly to the trace.

>>926176
That's true, but I've already attached the wire and it's working! Also, this won't give in to stress.

Now I just have to do the same with the rest of the connectors, or get some hot glue.

Problem solved.

at that point i think you are just trolling, but nevermind.
In this case, you have a "lifted pad". Like someone already said, solder a solid piece of wire from the circled area to the left pin (next to your 2). This will eliminate the need of the whole trace from the circle to 2 and will provide solid connection between them.
Just make sure (with a multimeter) you didn't bridge any connections before powering your audio amplified dildo for the first time after the repair.
