Desolder the two audio cables.

Put a few drops of flux over the tin of each solder.

Melt the tin with the soldering iron tip set at 320-350 degrees Celsius.

The tin should melt easily, freeing the cable.

Do not leave the tip of the soldering iron for more than 4-5 seconds continuously over the pad and do not raise the temperature too high, you may ruin the circuit board.

Clean the pitches.

Pass with the desoldering braid over the remaining tin, resting the soldering iron tip on top.

You can add a little more flux or use a tin remover pump.
