I'm curious...did the sound work for a long time prior to this? What happened just before the sound quit working?
Bad speakers can (and do) blow audio output circuits. More likely, headphone jacks become intermittent due to the connector getting banged around with headphones or external speakers attached. They break.

Replacing the jack can be (relatively) easy if the jack is on a small daughter-board...you can buy those and swap them out If the jack is mounted directly to the motherboard then you have to pull the entire thing apart, then unsolder the old one and solder in a new one. I do this kind of stuff for a living, and frankly I don't like doing it because of the risk something else goes wrong. If you're not experienced with de-soldering (that's the hard part) I wouldn't recommend attempting it on an otherwise-working laptop.

An alternative I normally offer is an external USB audio device. They're cheap and dead-simple to install, assuming you have an available and good USB port. The audio quality is variable.
