The part on the bottom is the Dock connector. It is a soldered part on the logic board and difficult to replace, unless one has the knowledge and tools of repairing very small parts. when you say that the sound does not work, double check your repair if it worked before. I am not quite sure where you connect the iPod speakers. If your iPod connects, syncs and you get sound while the iPod speakers are connected through a dock, then there is no problem with the audio circuitry.
