Fortunately, there is no electricity carried through the Cox Cable. The center wire carries an RF signal, (Like a radio antenna wire), and no electrical current. If you heard a pop, I would consider what other's have said, contact an electrician. It sounds like there was either a short circuit, or a transformer pop, that would have surged electrical current through your home's electrical system, THAT could have damaged computer components as well as other electronics. Also, the Cox Cable doesn't connect to your computer, another facet of this that points away from Cox cable causing you any issues concerning your computer or it's sound.
